The adsorption characteristics of C.I. basic blue 26 (BB26) from aqueous solutions onto H3PO4-activated carbons (ACs) produced from açai stones (Euterpe oleraceaMartius) and Brazil nut shells (Bertholletia excelsaH. B. K) were investigated in a batch system. The ACs were characterized by...
H3PO4, K2Cr2O7, HCl, and NaOH were purchased from Beijing Chemical Co. Ltd. The stock solution of Cr(VI) was prepared by dissolving an exact quantity of K2Cr2O7 in deionized water. The solutions containing Cr(VI) for adsorption experiments were obtained by diluting 1000 mg/L of stock ...
