Iron Removal from Water by using Cashew Nut Shell

Aleena R. Haneef | Sukanya S. Nair

Abstract: Cashew nut shell from the agricultural waste was used as the adsorbent for the removal of iron present in the water. The effect of various parameters such as particle size, adsorbent dosage, initial iron concentration, contact time, pH and temperature were studied. FTIR, Scanning electron microscopy and Energy-dispersive X-ray spectroscopy were used for the characteristic study of cashew nut shell. Pinnacle 900 H atomic absorption spectrophotometer was used for the analysis. Results of adsorption isotherm study shows that, Langmuir isotherm was best fitted to the experimental data. Pseudo second order equation was follows adsorption kinetics. Desorption study was conducted by varying the hydrochloric acid concentration. Based on the studys results showed that cashew nut shell was effectively used for the iron present in water.
