Abstract :

Detection of iron in water involve use of different reagents but ' dipyridyl along with citric acid was used as a field test in a modified way. Its extraction was studied by means of ion selective chelating resin synthesized from chitosan. The separation is carried out by column chromatography. IR spectra, nitrogen content [calculated by Kjeldahl method] and pH titration [using batch method] were made for resin characterization. Resin characteristic such as moisture
content, bulk density, specific bulk volume and ion exchange capacity were also determined by standard methods. Metal uptake analysis was done by batch method using atomic absorption spectrophotometer. The distribution coefficient values at different pH levels were determined from batch method. Fe[ll] showed maximum Dg value at pH 7.0 .

Abstract :

Densities, viscosities of some substituted heterocyclic drug (Ramipril) in 1, 4 dioxane were measured in the temperature range 303K to 323K. The viscosity was determined by John–Dole equation. The data has been used to calculate Gibb’s free energy change (G), entropy change (S), and enthalpy change (H).G and H are negative andS is positive which indicates the spontaneity of reaction according to thermodynamics.

Abstract :

In the carpet industry synthetic dyes and washing chemicals are used in huge quantity above the permit limit. On one hand these chemicals improve the quality of carpet and if do not manage properly and poured in the water reservoir have cumulative effect because of its non-degradable properties.Ghosia is a Town city of district sant Ravidas nagar Bhadohi. It is situated in between Kashi and Prayag.In this town several carpet industries and dye houses are found which are international fame. In this area carpet industries are used much water and released in polluted forms because the dye house emits several chemicals and dyes during the manufacturering and colorization of woolen and cotton yarns.

In present work the impact of the effluent of dye house of carpet industries was taken to study, situated in Ghosia Town (Sant Ravidas Nagar, Bhadohi) for this study two test plants wheat (Triticum aestivum–var-343) and Barley (Hordeum Vulgare Var-Jyoti) were taken. It was observed that the toxic effect of lead on growth and metabolism of germinating wheat and Barley. In this paper the seed germination and seedling growth the seed were selected for uniformity in size and weight. The surface of seed was sterilized with 0.1% aqueous solution of HgCl2. Further it explores the possibility of the treatment of waste dyeing water with the help of various methods.

Abstract :

A number of iron complexes of type [FeL4 (H2O)2](NO3)3 (Where, L=hetero cyclic nitrogen donor ligands, such as imidazole, pyridine, piperidine, piperazine, indole, benzimidazole, benzotriazole, triazole, quinoline, iso-quinoline, carbazole) have been synthesized and characterized. These complexes are soluble in ordinary organic solvents. The conductivity data show that these complexes are 1:3 electrolytes in nature. The IR spectra reveal the coordination of ligand to the central iron atom through nitrogen. The mass spectra show a distinct molecular ion peak and the base peak .The thermal decomposition studies indicate the presence of water molecules which are ligated to the central metal ion. The loss of water molecule and the decomposition of nitrate ion occur at 140oC. The successive removal of imidazole molecules from the complex begins after 100oC, finally leaving Fe3O4 as the end product
