The Efect of Calcination Temperature on Toxin Adsorption Materials for Diarrheal Diseases

The synthesis and characterization of kaolin as a toxin adsorption material for diarrheal diseases has been performed. Adsorption ability is one important factor in determining the effectiveness of the adsorbent. Each adsorbent has different strengths depending on the adsorption capacity of each. The kaolin has been calcined at 400 °C, 600 °C, and 800 °C. The purpose of this study was to examine the changing character of the kaolin after calcination on the adsorption capacity. The characterization of samples includes the analysis phase, density test, porosity test, and the adsorption test of metal timbale as a medium toxin. We concluded that the kaolin has the highest adsorption capability level is a kaolin has been calcined at 400 °C with characteristic are kaolinite phase containing, degree of crystallinity of 76.59 %, has a density of 2.6275 g/ mL, the optimum porosity of 75 %, and the adsorption capacity of lead metal of 99.7325 %. The adsorption capacity of kaolin have been calcined at 400 °C is much better than the kaolin without calcinations and expected to be more effectively used to cure diarrhea
