Abstract
Removing pollutants from aquatic ecosystems, especially from drinking water, has always been a major concern for scientists. Recent decades have witnessed the widespread application of natural compounds used as adsorbents to remove various pollutants. On the other hand, studies have proved nanotechnology to be an effective way of removing pollutants. A new type of sponge belonging to the family Demospongiae that has nano holes and is native to the Persian Gulf was investigated for the first time in the present study for use as an adsorbent to remove calcium, magnesium, cobalt, cadmium, and lead ions from water. For this purpose, adbsorption in sponges of different aggregate sizes, contact time, particle size, and ambient pH were measured. The results showed that the proposed sponge is capable of adsorbing the above-mentioned metal ions to various degrees. While small amounts of calcium, magnesium, and cobalt were adsorbed by this sponge, cadmium recorded a higher adsorption of 2.37 mg/g at pH=5. The highest adsorption level of 79.19 mg per gram of adsorbent was recorded for lead at a pH range of 4.5-5 with a mesh size of 230. This is the highest adsorption ever recorded for lead in the literature on selective separation of lead from the other ions.
