Popis:	The aim of this research was to extract cellulose from office paper waste and converted into carboxymethyl cellulose (CMC) based flocculant to treat methylene blue (MB) dye solution. The yield of extracted cellulose obtained was 62.17%. Three different CMC samples were prepared. Degree of substitution (DS) for CMC-1 is 0.6585, CMC-2 is 0.8124 and CMC-3 is 0.8946. This proved that CMC are substituted into cellulose structure due to the DS of the commercial CMC are in the range of 0.4 to 1.5. The coagulation flocculation process of the MB dye shows that the CMC-3 was effective for methylene blue dye removal with highest percentage (98.14%) at pH 9.0, flocculant dosage of 210 ppm with 100 ppm MB concentration solution.
