Effect of K+-modified biochar on the adsorption performance of methylene blue

Effect of K+-modified biochar on the adsorption performance of methylene blue

Using corn stalks as raw materials, modified corn stalk biochar (hereafter referred to as biochar) was prepared by phosphoric acid (H3PO4) activation modification, potassium hydroxide (KOH) loading K+ modification and carbonization. The structure of the biochar was characterized using SEM, BET, XRD,...
