dc.description.abstractTerminalia catappa leaves waste is a biomass waste that can found around at University of Riau area. It was used as a source of adsorbent. After carbonization at temperature 300 °C at time of 1 hour, biocharcoal of Terminalia catappa leaves waste was observed surface acidity by Bhoem’s titration. Water and ash content of biocharcoal of Terminalia catappa leaves waste were also identified. The result of the acidity of adsorbent is determined by Bhoem’s titration. The result showed that acidity of carboxylic acids that content by biochorcoal was most carboxylic acids biocharcoal was 2,3221 mmol/g be compared phenolics acid and lactonic acid each of 0,0580 and 0,0442 mmol/g. Percentage content of water and ash from biocharcoal was the 3,04 % and 13,83 %.en_US
