Abstract/Executive Summary

Bamboo cellulose is a non-dangerous, biodegradable polymer with high elastic, compressive quality thereby beneficial in commercial and pharmaceutical industries. However, preparing it involves a complex procedure of solvent dissolution. NaOH/urea solution is a common solvent for cellulose dissolution, but its efficiency varies with temperature and concentration. Thus, this study aims to synthesize evidence on the efficiency of NaOH/urea solution in bamboo cellulose dissolution; identify the most suitable concentration and temperature of NaOH/urea; and determine the relationships between its concentration, temperature and bamboo cellulose’ dissolution rate. Extracted data indicated the bamboo source sample, NaOH/urea concentration, temperature, and dissolution results from five databases and utilized Quality of Reporting of Meta-analyses (QUOROM) and Assessment of Multiple Systematic Reviews (AMSTAR) instruments for the studies’ quality assessment. Among the studies, 93% utilized the concentration ratio of 7:12:81; therefore, concentration’s minimal changes did not profoundly affect the dissolution, given the same temperatures. Out of fifteen studies, eight used -12°C affirming that minimal changes in temperature affect the dissolution results. The Chi-square test revealed that only temperature and concentration indicate a significant relationship (x2=5.793, P<0.10). The heterogeneity test displayed a small amount of heterogeneity (I2= 33.42%, P<0.10; I2= 1.8%, P<0.10) on the gathered data that may be clinically unimportant, making the data considerably homogeneous. Hence, this provides significant evidence validating the efficiency of 7:12:81 NaOH/urea aqueous solution at -12°C in the dissolution of bamboo cellulose.
