This study demonstrates the use of an ecofriendly activated carbon (AC) prepared from pea peels by chemical activation with zinc chloride for the biosorption of Cr (VI) from aqueous solutions. The pre
Effects of contact time on adsorption capacity of Cu(II) onto different adsorbents (adsorbent dosage= 0.5 g, contact time = 5, 10, 15, 25, 35, 50, 65 h, initial Cu(II) concentration = 300 mg L
