摘要

This study examines the properties of Black Cotton Soil (BCS), Sand Particles (SP), and Sugarcane Bagasse (SB) through various analytical techniques. It involves sequential preparation steps like washing, drying, and grinding. Isotherm analysis reveals Type IV adsorption/desorption characteristics for all samples. BET analysis determines monolayer volumes (Vm) as 12.849, 1.3294, and 0.5768 cm3 (STP)g−1 for BCS, SP, and SB, with energy constants (C) of 2535.1, 49.883, and 6.6705, respectively. Mean pore diameters (dp) are 4.0273, 7.2504, and 6.0617 nm. The specific surface areas (as,BET) are 55.925, 5.7861, and 2.5105 m2g−1. BJH plots reveal pore volumes (Vp) of 0.038943, 0.010058, and 0.004079 cm3g−1, and pore specific surface areas (ap) of 19.746, 5.2282, and 2.6624 m2g−1. Mesopore distribution peaks (dp,peak) are consistently 2.43 nm. MP plot analysis indicates total specific surface areas (a1) and external surface areas (a2) of 66.103, 3.7087, 0.3787 m3g−1, and 11.498, 5.1618, 0.8742 m3g−1, respectively. Total Vp for BCS, SP, SB are 0.024967, 0.0006499, and 0.0011581 cm3g−1, with micropore distribution peaks (dp,peak) at 0.60, 0.70, and 1.10 nm. FTIR analysis identifies hydroxyl, methyl, nitrile, carboxylic acids, aromatic, ether, and polysaccharides, indicating diverse adsorption applications. Energy dispersive X-ray diffraction identifies BCS as containing C, O, Al, Si, and Ca, SP as containing C, O, Al, Si, K, and Br, and SB as containing C and O with fiber structures.
