TECHNOLOGICAL EVALUATION OF CELLULOSE CARBAMATE SYNTHESIZED FROM RICE STRAW AND ITS UTILIZATION AS DYE ADSORBENT

Egyptian rice straw was subjected to pulping via alkali scouring followed by hypochloric bleaching. the obtained cellulosic pulp was allowed to react with two different amounts of urea at high temperature to obtain cellulose carbamate acquire nitrogen content of...
