摘要

The composition and hydrogel for water absorption and removal of metals in aqueous solutions. The present invention is a composite material consisting of the mixture of Polysaccharides from natural origin with clay, which in contact with water to form a hydrogel.The composite is prepared by mechanical mixing of Polysaccharides from the family Sapindaceae with argilomineral vermiculite dehydrated. These composite water absorbent can be used in several products, including disposable diapers, towels, absorbent and intimate.The hidrogu00e9is present a series of other industrial applications, among which may be cited: constituent in cosmetic formulations, the vehicle of medicinal products for the skin, soil conditioner, due to its high water retention capacity and resistance to desidratau00e7 They will be.Another important application of the composite consists in its ability of removal of metals in aqueous solution, which enables its use as a filter element for the treatment of natural or industrial effluents contaminated with metals.
