In this study, the conditions for removing phosphate from the aqueous environment of the residue containing zinc and iron in addition to lead, which is called as lead cake and formed during zinc production in çinkur plants in Kayseri was investigated. For this purpose, the effects of parameters such as cake dose, time, and environment pH and temperature and phosphate concentration on the removal of phosphate from aqueous environment with this cake were investigated. Using the obtained results, adsorption isotherms were obtained and some thermodynamic quantities were calculated. In the experiments, it was found that the phosphate removal efficiency is highly dependent on the pH and the lead cake dose. In addition, it was observed that phosphate removal complied with the Langmuir and Freundlich isotherm, and the equilibrium was established at the end of a period of 120 minutes. Approximately 75% of the phosphate in the solution can be removed by mixing the orthophosphate solution with a concentration of 100 mg-P /L with an original pH of 7.69 with lead cake at a dose of 30 g /L and contacting it for 120 minutes.
