| مستخلص: | Palm oil mill sludge (POS) is a type of solid left over after anaerobic digestion of palm oil mill effluent. At present, not much work has been reported in the literature on the feasibility of reutilizing this waste. In this study, biochar was prepared from POS. POS was pyrolyzed using microwave technique. Several types of palm oil mill sludge biochar (POSB) was produced by varying the microwave heating power from 100 W to 500 W and the pyrolysis holding time from 5 min to 25 min. The efficiency of the produced POSB was tested for Trimethyltin (TMT), arsenate (As), and zinc (Zn) adsorption capacity. The results of this study highlighted that POSB is able to adsorb Zn by the functional groups. The adsorption capacity of Zn was recorded as 44.5 mg/g. However, for TMT and As, the adsorption was very minimum i.e. about 3.3 mg/g and 5.6 mg/g respectively. It was suggested that poor performance of POSB was due to the anionic nature of TMT and As. It was concluded that microwave pyrolysis was not suitable for POSB preparation. [ABSTRACT FROM AUTHOR] |
