Biosorption of copper (II), iron (II) and zinc (II) from synthetic waste water using Banjh leaves as low cost adsorbent

Naveen Chandra Joshi, N.S.Bhandari, Sanjay Kumar


In the present study Banjh leaves (Quercus leucotrichophora) have been used for removal of copper, iron and zinc from synthetic waste water in batch system. Various biosorption parameters such as contact time, dosage, pH, concentration and temperature have been used. The maximum biosorption efficiency achieved at optimized conditions such as high dose of adsorbent, high pH and low concentration of metal ions. The adsorption of metal ions increases with time. The Banjh leaf powder is able to achieve the percentage removal for copper, iron and zinc are 17.50, 44.78 and 22.14 after 25 minutes at amount of adsorbent 1g and pH 3. The removal efficiency of copper, iron and zinc achieved 75.32, 60.70 and 60.81 after 25 minutes at pH 5. The removal efficiency of copper, iron and zinc achieved 22.71, 49.12 and 24.61 at 75OC. The equilibriumdata of adsorption have also been tested with Langmuir, Freundlich and Temkin isotherm models. The value of correlation coefficient (R2) and other parameters have been evaluated.
