Performance evaluation of zirconium silicate composite for removal of cadmium and zinc ions

The purification of wastewater is preferred using the adsorption by column due to process’s high efficiency. Column investigations are performed remove hazardous pollutants and demonstrate efficiency in treatment process. Cadmium zinc exist radioactive industrial wastes. Therefore, this work interested cadmium removal from utilising a fixed-bed column. Zirconia–silicate composite (ZrO2–SiO2) was synthesised sol–gel technique analyzed for purpose. influence some parameters as bed depth (2.0, 3.0 5.0 cm), flow rate (2.0 mL/min) initial ions concentrations (50–200 mg/L) investigated. performance computed be 80.3 79.3% Zn2 + Cd2+, respectively, at optimum conditions (3.0 cm depth, 2.0 mL/min 100 mg/L concentration). Thomas, Adams–Bohart Yoon–Nelson theories were assess breakthrough curves determine models which essential scale-up design. Thomas theory exhibited highest R2 values (0.84–0.97) gave most accurate computation
