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...

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 0.13 and 0.16 on using 10 and 20 g urea/100g cellulose pulp respectively. The obtained carbamate derivatives were evaluated as dye adsorbent for different reactive dyes. Different factors were investigated as the nature of colour used, the technique applied, the time of treatment, and concentration of dyes used. It was found that the magnitude of the adsorbed colour depends on the N %, whereas the %N increases the % colour removal increases too. As the concentration of the dye increases from 0.01 to 0.5g/ 1000ml, the colour removal % decreases regularly. It is clear from the obtained results that the % colour removal as well as the time to reach the maximum colour removal percent depend on: a) the natureof the reactive dye used, (b) the degree of carbamation expressed as % N and (c) the technique applied. |
