The application of the zero residues level in the removal of tin (II) cations from wastewater using tangerine peels via adsorption technique was the main objective of the current study. A batch-type adsorption unit was used to detect the optimal operating conditions that conducted the maximum percentage removal of target cations. The effect of six major design parameters on the recovery efficiency of tin (II) cations from contaminated aqueous solutions was investigated. Experimental results showed that more than 90% was the maximum tin (II) cation removal efficiency achieved at 150 minutes, 4.5 ppm, 400 rpm, 50°C, and 5.5 and 6 g for contact time, initial concentration of tin (II) cations, agitation speed, temperature, pH, and tangerine peels dosage, respectively. The study also indicated that the treatment efficiency is directly proportional to the agitation speed, the adsorbent dosage, the temperature and the contact time, while the proportional with the initial concentration of tin (II) cations was inversely. The effect of acidity was consistent, being directly proportional within the acidic ranges, and inversely proportional within the basic range.
