Exploitation of expired cellulose biopolymers as hydrochars for capturing emerging contaminants from water

Abstract

From expired cellulose to hydrochar adsorbent for water contaminants.

Environmentally safe biopolymer-clay composite for efficient adsorption of ciprofloxacin in fresh and saline solutions

“…The combination of chitosan and bentonite imparted an overall neutral charge to the composite at the studied pH which favors physical interactions like van der Waals to occur. Thus, the shielding action of NaCl is diminished owing to the overall neutrality of the composite [ 44 ]. To examine the stability of the composite in saline conditions, the composite was weighed before and after adsorption it showed an increase in weight by 5.66% that is equivalent to the amount of CPX adsorbed, thus indicating the stability of the composite.…”
