The adsorption mechanisms of SMB are identified for its potential to increase soil-pH and reduce available cadmium (Cd). The study reveals the potential of BC and SMB in immobilizing Cd in contaminated soil. SMB demonstrated the highest adsorption capacity for Cd, followed by BC, PSM, and compost, with capacities ranging from 7.47 to 17.67 mg g^-1. Both BC and SMB exhibit high adsorption capacities (12.82 and 17.67 mg g^-1, respectively) and low desorption percentages (4.46-6.23%) at ion strengths of 0.01 to 0.1 mol-L^-1 and pH levels ranging from 5 to 7. SMB showed a higher adsorption capacity (17.67 mg g^-1) and lower desorption percentage (4.46-6.23%) compared to BC. The adsorption mechanism involves surface-precipitation, ion exchange, and the formation of Cd(OH)₂ and CdCO₃ precipitates, as well as interactions between Cd and organic sulfur, leading to more stable-Cd and CdHS⁺ compounds.

The variables that have been identified include pH, dye concentration, process temperature, adsorbent amount, and particle size of the adsorbent. To obtain information on the adsorption process and to design the mechanism of the adsorption system on experimental equilibrium, 10 isotherm models, namely, Langmuir, Freundlich, Jovanovic, Dubinin-Radushkevich, Sips, Redlich-Peterson, Toth, Vieth-Sladek, Brouers-Sotolongo, and Radke-Prausnitz were applied. It was discovered that the experimental adsorption capacity, <i>q_e</i>, was roughly 110 mg g^-1. The result has a maximum adsorption of 136.17 mg g^-1 as predicted by Dubinin-Radushkevich isotherm. Diffusion film models, Dumwald-Wagner and Weber-Morris models, and pseudo-first- and second-order models, were used to determine the adsorption kinetics.
