Biomass systems are based on a wide range of feedstock, like food and agricultural waste. The quest for bio-adsorbents that are environmentally benign is the rationale for this study. Thus, the research is aimed at the isolation, physicochemical, and BET analysis of cellulose obtained from Pentaclethra macrophylla Benth Pod (PMBP) biomass waste. The powdered PMBP was dewaxed with toluene and ethanol (2:1) and, thereafter, treated with aqueous sodium hypochlorite (7.5% at 70oC) and sodium hydroxide (17.5%w/v at 80oC) to obtain isolated cellulose. Proximate, ultimate, and chemical composition analysis reveals the presence of cellulose (42.7%), hemicelluloses (7.8%), lignin (38.5%), silicon (40.72%), aluminium (17.10%) and elements. The FTIR and Raman spectroscopic analysis revealed some of the functional groups associated with isolated cellulose and raw PMBP. The presence of hemicelluloses and lignin in the isolated cellulose implies that the isolation process did not remove all the impurities. The BET analysis reveals a better specific surface area, pore volume, and average pore diameter or size of the isolated cellulose, and could serve as a better adsorbent than the raw. As a result of the increased surface area and high percentage of isolated cellulose in PMBP, it can be used as a sustainable energy source as well as for the environmental remediation of heavy metals.
