The research about adsorption and desorpstion of Mn2+ in of chitincellulose adsorbent has been carried out. Chitin was extracted from snail shell and cellulose from plant rice. Characterization of chitin and cellulose was conducted by determination of water and ash content. Adsorption of Mn has been in chitin, cellulose and modification of chitin cellulose has been studied through determination…
