    Minimization of dyestuff pollutions using native, alkali-treated or bleached cellulose of rice straw as adsorbent
    (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2013) Abd El-Thalouth, I.; El-Hennawi, H. M.; Abd El-Salam, S. S.; Adel, E.
    Cellulose rice straw pulp has been prepared via alkali scouring and wscouring+ bleaching and then used along with the raw material as dye adsorbents for some selected reactive dyes. Factors affecting dyestuff adsorption such as technique applied (mechanical shaking and ultrasonic), time, temperature, amount of substrate and concentration of the dyestuff have been thoroughly investigated. It is found that % colour removal depends on (i) nature of reactive dye used, (ii) degree of purity of adsorbent i.e. either native, alkali-treated or bleached cellulose, and (iii) technique applied during dye adsorption.
