Besides having advantages, Chitosan as biosorbent has also disadvantages. . Chitosan is very soluble in low pH so it cannot adsorb Cr (total) at low pH. It is due to active site (amine group) of chitosan undergo protonation and its adsorption capability is easily influenced by anions in waters. The research studied use of chitosan coating active charcoal of coconut shell to increase adsorpti…
