Abstract
Removal of Cr(VI) from aqueous solution by Date-Palm-Leaves (DPL) and Broad-Bean-
Shoots (BBS) was investigated. FTIR, SEM, and EDAX showed that DPL has higher ability
for ion-exchange to remove Cr(VI). Langmuir and Freundlich adsorption isotherms and
kinetics revealed that DPL exhibited higher biosorption capacity. At Cr(VI) 100 mg/L,
biosorbent-dose 5 g/L and 60 min contact-time, maximum Cr(VI) removal for DPL (98%)
and BBS (95%) was achieved at pH 2 and 1, respectively. Adaptive-neuro fuzzy inference
system determined the most important factor affecting Cr(VI) removal. The model
indicated that DPL is more tolerant to pH levels, while BBS is a pH-sensitive adsorbent.
