The present work is aimed to investigate the feasibility of leaf biomass of Bambusa vulgaris for removal of Arsenic (As) in contaminated water. Different weight of leaf biomass were treated with As contaminated water sample to observe the biosorption/ adsorption capacity of Bambusa vulgaris leaf biomass. Concentration of As was decreased by 55% after treating 8 gm Bamboo leaf biomass for 4 hrs. The multivariate ANOVA of the recorded data also indicates that the treatment of Arsenic contaminated water through the bamboo leaves can be applied with promising result. Pearson correlation analysis also shows that all the treatments are positively significant with respect to the mass of the used botanical tool and also with respect to the time. The work demonstrates that Bambusa vulgaris leaf biomass can be a suitable botanical tool for phytoremediation of Arsenic contaminated water.
