01. Study on hydrochar production from cassava residue for phosphate removal from water

Mai Vũ Thị, Thủy Trịnh Thị


Cassava bagasse is a by product generated from starch-manufacturing and it contains high levels of organic matter that likely to cause environmental pollution. Hence, there have been many studies on the utilization of cassava residue. This study investigated the suitable condition for creating hydrochar and modified hydrochar with MgCl2 from cassava residue and found that the optimum heating temperature were 200oC for 1 hour. Studied SEM-EDX image showed that Mg nanoparticles were attached on hydrochar surface, which made the phosphate adsorption efficiency of the modified MgCl2 (75.24%) higher than that of normal hydrochar (54.91%). The phosphate adsorption of Mg-attached hydrochar were optimal at pH 4 and the optimal retention time of 150 minutes. The maximum adsorption capacity of modified hydrochar based on Langmuir were 15.15 mg/g. This is a promising orientation for the use of waste cassava residue to produce hydrochar for phosphate removal from wastewater.
