Abstract

In this research, some agricultural wastes such as sugarcane bagasse, rice straw, wheat straw, sawdust and leaves of palm tree for production of CarboxyMethyl Cellulose (CMC) are investigated. Also, the effect of NaOH on these sources to obtain the maximum Degree of Substitutions (DS) was studied. The results showed that the maximum DSs were 0.71, 0.58, 0.41, 0.67, and 0.54 for sugarcane bagasse, rice straw, wheat straw, sawdust, and leaves of palm tree, respectively.  Also at this condition, viscosity of produced CMCs  ( 1 % w/w ) were measured   6.84, 10.8, 4.97, 4.08, and 7.71 cp for sugarcane bagasse, rice straw, wheat straw, sawdust, and leaves of palm tree at, respectively. To confirm the Carboxymethyl Cellulose production, the FT-IR of commercially obtained purified CMC and CMCs of this study were compared. According to our work, these results suggest that the agricultural wastes are appropriate candidates for production of CMC in different industries.
