Abstract
Water decontamination using adsorbent materials has been studied extensively and reported in the literature. Readily available and less expensive material can be used to prepare efficient adsorbents. Dried leaves of Millettia pinnata are not only readily available but also rich in hydrocarbon content. This stimulated us to prepare activated carbon from Millettia pinnata and investigate its adsorbent activity using colorimetry. In this present study, the adsorption efficiency of methylene blue on commercial and test carbon using batch adsorption process is reported. Effect of adsorbent dose and contact time are analyzed and Langmuir’s adsorption isotherms constructed. It is observed that as the concentration and contact time of adsorbent increases, there is a marked enhancement in the percent adsorption of methylene blue. This is confirmed in colorimetric spectra of both commercial and test carbon.
