Utilization of a Newly Developed Nanomaterial Based on Loading of Biochar with Hematite for the Removal of Cadmium Ions from Aqueous Media

In order to conserve the energy used for remediation of harmful metals from aqueous media, an adsorption process was performed. It is efficient and low-cost method with zero carbon emissions as compared other methods. A hematite-based novel nanomaterial loaded onto biochar utilized toxic cadmium metal ions media. Saccharum munja has been employed feedstock prepare biochar. Three adsorbents i.e., raw (SM), (SMBC) hematite-loaded bichar (HLSMBC) were in batch tests study uptake by optimizing experimental parameters. Experimental data calculated results revealed maximum sorption efficiency Cd(II) removal given HLSMBC (72 ppm) SMBC (67.73 SM (48.7 ppm). Among isotherms applied on work best fit found a Freundlich isotherm high values correlation coefficient R2 ? 0.9 all sorbents constant 1/n between 0–1. Equilibrium evaluated using five different types errors functions. Thermodynamic studies suggested feasible, spontaneous endothermic nature process, while, ?H parameter < 80 kJ/mol indicated physiosorption positive ?S promoted randomness increase process. Data fitted into type I pseudo second kinetics having 0.98 rate constants K2 (0–1). Desorption also performed storage, conservation reuse sorbent sorbate materials.
