Chitosan-functionalized magnetic peanut shell biochar composite for efficient adsorptive removal of Congo red from aqueous solution.
Synthetic dye discharge into aquatic systems has become an escalating environmental concern because these colorants are chemically recalcitrant, toxic, and resistant to biodegradation. In the present study, a Chitosan-functionalized magnetic peanut shell biochar composite (CS-MPSB) was engineered as an economical, biom...
