Abstract :

Structural characterization of microemulsions in a pseudoternary system, Triton X -100+1-penanol (1:5 molar ratio)/ n-hexane/ brine system has been done by using different techniques such as quasielastic light scattering (QELS), conductivity, viscosity and crossed polaroid microscope. Different distinct regions such as 1 micellar region, a two-phase region and a very narrow three-phase region were observed in the pseudo-ternary phase diagram. Electrical conductivities and viscosities of the system with different weight fraction of water (w) were determined and results were used to locate sub-regions of the single-phase microemulsion. The results showed that a transition from water-in-oil microstructure via bicontinuous structure to an oil-in-water microemulsion region occurred with increase in weight fraction of water w in the system. The size of the microemulsion droplets was determined by quasi–elastic light scattering. It was found that the sizes of the droplets depended markedly on weight fraction of water (w) and were in the range of 16-38 nm. In the upper portion (at s > 70) of the isotropic region of the phase diagram, the structure of microemulsion droplets is unclear.

Abstract :

Dibenzyl sulphide forms stable complexes of composition [MX5(R2S)] (M=Nb/Ta; X=Cl/Br; R=C6H5CH2) and [NbOX3(R2S)2] (X = Cl/ Br; R = C6H5CH2). The compositions of the complexes have been established by elemental analysis, magnetic susceptibility measurements, conductivity, IR, UV-vis and 1H NMR spectral data. These complexes are seven-coordinate and halogen-bridged or oxygen-bridged pentagonalpyramidal dimeric structure.

Abstract :

Synthesis, Spectral Characterization and Antimicrobial screening of some mixed ligand complexes of Co(II), Ni(II), Cu(II), Ru(II) and Zn(II) with tribenzyl phosphine and anthranilic acid are investigated. The octahedral structure of bis-chelates are deduced using elemental analyses, conductivity measurements, IR, UV-vis and 1H NMR studies. Anthranilic acid acts as mononegative bidentate chelating anion with these bivalent metal ions. The antimicrobial activities of ligand and complexes against three types of pathogenic bacteria, Staphylococcus, Klebsiella ssp and Bacillas are examined

Abstract :

Fairly air stable organoruthenium (II) complexes having spectral formula [RuH(CS)(P3)n(APMTH)n 1(Py)n 11Cl] (where n=3,2,1,1; n1= 0,1,2,1 and n11=0,0,0, 1 respectively) have been prepared and characterized using various physico-chemical methods. All these complexes are found to be non-electrolytic and diamagnetic in nature. The ligand and its metal complexes are screened for their antifungal activities against A. niger and these may be classified as mixed antifungal agents.

Abstract :

Oil quality characteristics of Cultivars sinnensis and Citrullus lanatus seed oils were investigated using standard techniques. The physico-chemical analysis revealed the colour to be (yellow, reddish brown), specific gravity (0.92 ± 0.01, 0.94 ± 0.02), pH (3.88, 5.21), acid values (82.00 ± 2, 93.18 ± 1 mg KOH/ g), iodine values (108.00 ± 3, 103.61 ± 2 mg iodine/ g), peroxide values (22.84 ± 1, 30.00± 1.5meq/ kg) and saponification values (192.00 ± 1, 208.50 ± 3 mg KOH/g) respectively. These properties indicate that the oils will be very useful industrially for the manufacture of products such as paints, liquid soaps and shampoos. The four most abundant fatty acids were; C18:26 > C18:19 > C16:0 > C18 : 0 in the two oils. Unsaturated fatty acids predominated in the sample with adequate amounts of essential fatty acids.

Abstract :

Because of sharply develop of textile dyeing industries across the world, there is widely used of heavy metals in textile dyeing industry which cause significant effects on environments. Various adsorbents have been used to remove heavy metal ions from textile waste effluent. Rice husk, sand, clays, baggase, tea waste, fly ash etc are among the
common adsorbents used, mixture of sand and fly ash in acidic medium is a good adsorbent to remove the heavy metal ions from textile effluent(dyeing and finishing process waste water). The Adsorption is an effective and successful technique for removal of heavy metals from effluent received from textile dyeing industries. This work introduces the feasibility of using mixture of sand and fly ash in presence of hydrochloric acid. The adsorbent order of metal uptake capacities in μmol g-1 for extraction of five metals ions from aqueous solution using adsorption techniques is Cu(II)>Pb(II)>Cr(II)>Zn(II)>Co(II). In this study, adsorbents sand and coal fly ash, available as natural resources in all areas of our country are examined as viable materials for treatment of Cu,Pb,Cr,Zn & Co containing in textile dyeing and finishing process effluent at controlled pH. The results obtained from this study revealed a relative ability of mixture of sand and fly ash in presence of hydrochloric acid and totally depends on pH,concentration of solution, adsorbent dose, size of the particles of adsorbent, temperature and time.

Abstract :

The oxidation of mixture of Oxalic acid + Malonic acid in presence of Hydrochloric acid in aqueous medium is reported here. The reaction is of first order with respect to each substrate; oxidant and [H+] The oxidation of mixture of acids was studied at different concentration of HCl. The products are CO2 and carbonyl di carboxylic acid. The rate constant increases with increase in concentration of added acid .The rate constant, catalytic constant, dielectric constant and effect of temperature were also determined. Various thermodynamic parameters like energy of activation, frequency factor were also determined. A mechanism consistent with result obtained has been proposed with the following rate equation:

SANTOSH KUMAR*, MANOJ RANJANa and ABHAY KUMARb

Department of Chemistry, A.GP.G.H.S Gopalganj-841428 India

Abstract :

2525 KM long Ganges enters at Buxar in Bihar and exits at Rajrnahal covering a distance of nearly 560 Km. Nearly four lacs people reside in this heavily industrial zone - i.e. Bata India Ltd. at Mokama, Me Dowell Distillery at Hathidah, Barauni Thermal Power Station, Hindustan Fertilizer Co. Ltd. and” Indian Oil Refinery at Barauni. It is estimated that 6,420 m3/d (cubic meter) per day of domestic wastes and 48,240 m3/d of industrial effluent are being generated by these industries, which are directly discharge into the river Ganga. 

Keeping in view the above background a modest attempt to evaluate and analyse the pollution load in Ganga river around Rajendra Bridge at Mokama in the vicinity of Barauni - Mokama industrial complex with special emphasis on the pollution of the river causedby the discharge of industrial effluents.
