Description
Summary:A new nano-silica/chitosan (SiO<sub>2</sub>/CS) sorbent was created using a wet process to eliminate uranium(VI) from its solution. Measurements using BET, XRD, EDX, SEM, and FTIR were utilized to analyze the production of SiO<sub>2</sub>/CS. The adsorption progressions were carried out by pH, SiO<sub>2</sub>/CS dose, temperature, sorbing time, and U(VI) concentration measurements. The optimal condition for U(VI) sorption (165 mg/g) was found to be pH 3.5, 60 mg SiO<sub>2</sub>/CS, for 50 min of sorbing time, and 200 mg/L U(VI). Both the second-order sorption kinetics and Langmuir adsorption model were observed to be obeyed by the ability of SiO<sub>2</sub>/CS to eradicate U(VI). Thermodynamically, the sorption strategy was a spontaneous reaction and exothermic. According to the findings, SiO<sub>2</sub>/CS had the potential to serve as an effectual sorbent for U(VI) displacement.
