Statistical optimization of for chromium (IV) removal on aqueous solution using chitosan

In this work, a statistical model which can be used to evaluate the removal of chromium from aqueous solution using chitosan as an adsorbent has been developed. The experiment was described by varying chitosan dosage (10-30 mg), pH (5-8), contact time (10-90 min) and agitation speed (50-250 rpm). T...
