Summary: Biochar has been found to be an effective carrier for microorganisms due to its physicochemical properties and microenvironment. In this study, the adhesion behavior of Bacillus salmalaya 139SI and Bacillus amyloliquefaciens NBRC 15535 on oil palm kernel shell (OPKS) biochar was investigated. The pseudo-second-order kinetics model accurately described the adhesion process, and the adhesion equilibrium was reached after 80 minutes with a cell concentration of 10^8 CFU/g. Field Emission Scanning Electron Microscopy images revealed the formation of microcolonies and a biofilm structure on the biochar surface, and electron dispersive spectroscopy analysis suggested that bacteria attached to mineral-rich regions on the biochar surface, which may enhance their survival.

Summary: In this study, zeolite sodalite SOD, LTA, and FAU of different structures were successfully synthesized. The morphological analysis showed that the samples exhibited different shapes. The N2 adsorption-desorption studies indicated that the synthesized samples corresponded to adsorption types IV and I. CO2 adsorption experiments revealed that the zeolite FAU had the highest adsorption capacity. The synthesized zeolites were found to have a large electric field gradient, allowing them to strongly adsorb CO2 molecules.

Summary: Analytical isotherm models are commonly used for modeling adsorption studies, but most of them do not consider the pH-dependent adsorption. The modified Langmuir-Freundlich (MLF) isotherm model developed by us can simulate pH-dependent adsorption. In this study, the MLF model was extended to other metal ions by considering chromium adsorption datasets on different adsorbents.
