Removal of Cadmium (II) from Water by Adsorption on Natural Compound
The removal of a high level of cadmium in drinking water by Guava leaves as a natural material is a simple way to produce high-quality water. The study revealed that Guava leaves were able to effectively remove a significant percentage of cadmium. Using a 0.5 gm sample size of ground Guava leaves could remove 90% of cadmium with an initial concentration of 100 ppm within 120 min. A significant increase in the removal of Cd (II) with an increase in the Guava dosage and increase in temperature could be observed. There is a remarkable efficiency for Guava leaves in the range of cadmium concentration of 50 to 250 ppm. Time 120 minutes is the suitable contact time of adsorption that achieves the highest cadmium removal from water. The optimum pH for having the highest amount of cadmium removal was around 6. It is obvious that the 0.5 mg dose is the most efficient adsorbent dose, and the ideal temperature is 25-30 oC.
