Fig. 4From: Enhanced phosphate adsorption and desorption characteristics of MgO-modified biochars prepared via direct co-pyrolysis of MgO and raw materialsPO adsorption kinetics for MRS, MCS, MOT, and MGW. Symbols indicate the experimental data, and the lines indicate the results of the simulations based on the pseudo-first-order and pseudo-second-order modelsBack to article page
