The goal of this study was to utilize low cost and environmentally friendly adsorbents for batch scale removal of Amaranth dye from aqueous medium. Peels of Pisum sativum (Pea) and Arachis hypogaea (Peanut) were utilized to investigate their dye removing capacity. The optimized adsorption conditions for Pisum sativum (P.S.P) and Arachis hypogaea (A.H.S) were: adsorbent dose; 0.6 and 0.4 g, contact time; 45 and 10 minutes, pH; 2.0 for both, agitation speed; 150 and 100 rpm and temperature; 60 and 50 0C for P.S.P and A.H.S respectively. The adsorption data well suited to Langmuir isotherm. Maxim..read more
