A method of removing arsenic and heavy metals from water using metal salt hydroxide~gels is provided. The arsenic present in water is adsorbed onto the hydroxide-gels which can effectively be filtered through a diatomaceous earth (DE) filtration bed. The combination of DE mixed hydroxide-gels is also effective in removing arsenic from water and heavy metals from water.
Cette invention concerne un procédé permettant d'éliminer l'arsenic et les métaux lourds dans l'eau à l'aide de gels d'hydroxyde de sel métallique. L'arsenic présent dans l'eau est adsorbé sur les gels d'hydroxyde qui peuvent être efficacement filtrés à travers un lit filtrant à terre de diatomées (DE). La combinaison de terre de diatomées mélangée à des gels d'hydroxyde est également efficace pour éliminer l'arsenic et les métaux lourds présents dans l'eau.
