Investigating the Removal of Cadmium from Aquatic Solution with Apple Peel Absorbent

Potential risks have been well known for health which recognized with toxic heavy metals in environment. Cadmium is one of the most important heavy metals that its presence in aquatic environment have created many concerns due to high toxicity at low concentrations and the ability to accumulate in living tissues. Therefore, the aim of this study was to determine the rate of removal of cadmium from aqueous solution with apple peel absorbent as an inexpensive absorbent . This study is an experimental study . Samples are prepared synthetically and the PH parameters, contact time and cadmium ion counts are investigated. The results are plotted using Exce l software . The results showed that the initial concentration of cadmium sulfate was 20 mg/L, the best pH was 5, the best absorbent dose was 1.5 g / l, and the contact time was 15 min, with the highest removal percentage of 98%.The results showed that the parameters of initial concentration of cadmium, pH, adsorbent concentration and contact time are effective in eliminating the amount of removal . This Study showed that the apple peel absorbent as an inexpensive absorbent, is effective in removing cadmium .
