Triethanolamine concentration, leaching temperature, solid-to-liquid ratio, and leaching time has been selected as variables. A model has been obtained among relevant parameters by means of variance analysis by using the Matlab Computer Software Programme. The optimum conversion conditions for process are found to be a triethanolamine concentration of 3.5 M, leaching temperature of 313 K, solid-to-liquid ratio of 1/10, and leaching time of 150 min. Under the optimal conditions, the removal of lead is obtained as 87.67%. It is observed that the model obtained has nearly fitted the full second-order model, and the correlation coefficient calculated at 95% confidence level has a value of 0.97.
