The Study of Modified Bonechar Synthesis to Apply in the Treating Alum Water in KienGiang Province

Abstract

In this research, bone char was synthesized going from bovine bone waste which collected at cooking shop of noodle soup with beef in Vietnam country, called as Vietnamese bone char (VNBC).  In VNBC synthesis, the results of synthesis process were found the VNBC product sample with the optimal calcination condition to be at temperature of 600 oC, corresponding to the time of 90 minutes. Further, the characteristics of VNBC product sample were analyzed with the specific surface area of 76.404 m2/g, and pore diameter of 87.48 Å measured by BET method. The surface morphology with the particle size measured by SEM method was 70 nm. The composition compounds of VNBC contained calcium carbonate-hydroxyl apatite with the formula was Ca5(PO4)3(CO3)(OH) measured by FT-IR and XRD methods, respectively. In application, VNBC uses as adsorbent to treatment the alum water sample collected at KienLuong region of KienGiang province were considered. The results of VNBC adsorbent to treat alum water solutions measured by UV/VIS method obtained the conditional indicators after alum water adsorption are in agreement with the cleaned water of Vietnamese standard. These results suggested that VNBC are able to use making a potential adsorbent in the treatment of alum water resource becoming clean water resource in Vietnam
