Effect of â€œPanchakavya ghirtaâ€ against Chlorotic Leaf Spot Disease in Oryza Sativa L
Legislation about toxic substances in industrial waste waters is becoming increasingly strict. Consequently, a large number of researches are addressing the variety of issues in this area. Dyes are common constituents of effluents discharged by various industries. The present study was undertaken to find out a suitable low cost, environmental friendly and highly effective bio-sorbent to remove malachite green from aqueous solution. The effect of temperature on the equilibrium adsorption of dye from carbon was investigated. The euqilibrium adsorption data was analysed using two widely applied isotherms, namely, Langmuir and Freundlich isotherms. A non-linear method was used for compsring the best fit of the isotherm. Both the isotherms were found to be fit. Thermodynamic parameters such as , were calculated using adsorption equilibrium constant obtained from the Langmuir isotherm. From kinetic reversible first order kinetics were studied. Results suggested that the malachite green adsorption on CBC was a spontaneous and endothermic process.
