Daftar Isi:
- Water hyacinth is a weed growth on shallow water, ponds, lake and it is growth fast so it can give negative effect in the enviroment. Many efforts has been done to reduce amount of water hyacinth. The prime component on cell wall of water hyacinth is cellulose, so it can be a alternative source of cellulose and it can be modified to be cellulose derivatives, one of them is carboxymethyl cellulose (CMC).The aims of the present study were to get method of isolation of cellulose from water hyacinth and synthesize of CMC. The research was conducted in two main steps: isolation of cellulose from water hyacinth and synthesize of CMC. Firstly, Isolation of cellulose has been done using NaOH 10%, 12.5%, 15%, and 17.5% at 100�C for 3 h (1:20 w/v) and resulted pulp. The pulp was bleached for twice by NaOCl and natrium metabisulfit, each bleached for 3 h at 60�C and then dried, milled and resulted cellulose powder. Secondly, synthesizing of CMC in which there were three variables on this research, concentration of NaOH (x1
