See What I Found After Oven-Drying
I had informed in my previous post that I would unveil to you what I am up to, this semester. I had also told you that I would tell about what I am working on, in conjunction with my mentor, who is also my senior colleague. To begin, Sis. Beatrice works on biochar-supported phosphate as fertilizer, where in she added some amount of anhydrous magnesium sulfate as well as potassium dihydrogen phosphate. I am doing something similar too. The difference is the compound(s) that serve(s) as the activating ingredient. Rice husk is a biomass feedstock with high surface area, and this characteristic per se makes it a good agent for biochar use. I took some grams of rice husk biochar dissolved in de-ionized water, activated with calcium chloride and potassium dihydrogen phosphate with some stirring at temperature 35-40 deg. C, for a period of 30 mins for each of the activators. The significance of activating with compounds as calcium chloride or magnesium sulfate is to increase the porosity...
