This study demonstrates peanut shells as a potential inexpensive and ecofriendly adsorbent for adsorption of streptomycin drug from aqueous solution via batch adsorption method. Reaction isotherm studies were carried out at several experimental conditions of concentration of streptomycin drug (10-100 mg/g), adsorbent dosage (0.1-2 g), equilibrium time (5-60 min), and solution pH (3-10). The adsorbent surface was characterized via field emission scanning electron microscopes (FE-SEM) and transmission electron microscopy (TEM). The best adsorption efficiency of drug on to peanut shells was observed as high as 1.677 mg/g. The removal percentage % of streptomycin drug rise with increasing weight of peanut shells as well as solution of pH. Equilibrium of streptomycin drug on to peanut shells rind is found to be quick, and equilibrium to reached in 60 min. Langmuir isotherm and Freundlich isotherm models were useful to fit the result of equilibrium peanut shells, and it was noticed that isotherm Freundlich fits the multilayer peanut shells ability for drug was 1.455 mg/g. These data demonstrated that peanut shells are locally available, ecologically, effective and inexpensive adsorbent for the adsorption of Streptomycin drug from aqueous solution.
