In the present work, the medicinal plant leafs of Raatrani treated with sulphuric acid and formaldehyde were used as an adsorbent for the removal of acid blue, acid red and malachite green from aqueous solution. The adsorption characteristics of all the three acid dyes on activated Raatrani leaf powder (RLP) were evaluated as a function of pH, adsorbent dose, initial concentration of adsorbate and temperature. The effective adsorption was found to be in pH range 3.5 to7.2, adsorbent dose 0.5gms to 0.8gms, initial concentration (1x10-5 to 5x10-5M) and temperature range (308 to 318K) The results reveal that maximum adsorption of all three acid dyes onto RLP is within the range of 58.70% to 83.70%. The adsorption data fitted well into Freundlich and Langmuir adsorption models. The results show that Raatrani leaf powder holds a great potential in removal of acid dyes from industrial wastewater.
