The objective of this work is to study sustainable process which benefit environment by using agricultural waste as adsorbent to remove organic pollutants from water. As the current worldwide trend towards more precise environmental standards, technical aptness and cost-effectiveness became key factors in the selection of adsorbents for water and wastewater treatment. Recently, various low-cost adsorbents procure from agricultural waste, industrial by-products or natural materials, have been rigorously investigated. In this we utilize the agriculture waste i.e. Alisma plantago aquatic, rice husk, saw dust, tea and coffee waste, orange peel , peanut shells, activated carbon ,dry tree leaves and barks, bagasse, fibre, leaves and peels are use as adsorbent which can offer an economical solution for wastewater treatment. Three adsorption isotherm models namely Freundlich, Langmuir and Dubinin-Radushkevich were apply to analyse the equilibrium data. Equilibrium is best described by Langmuir isotherm model (R2≈1). Isotherm studies have been used to verify the thermodynamic parameters of the process. Kinetic parameters of adsorption such as pseudo first order, second order and intraparticle diffusion rate constant were determined and fitted with second order kinetic model. Adam Bohart and Wolborska models were applied to the experimental data obtained from dynamic studies on packed bed and were observed to fit the data well with good correlations. The model parameters, including the mass transfer coefficient and kinetic parameters were estimated.
