Adsorbents for removing arsenic and selenium from water

摘要

according to the invention contain amorphous adsorbents respectively as ternary hydrated oxides of fe ti, now in the molar fe.sup.3 +.n.: ti.sup.4 +.n.1 to 3: 3 to 1, and the content of the kremu00edku in relation to the total weight of zeleza titanium kremu00edku is at an interval of 5 to 25% by weight.amorphous hydrous oxides of fe and ti respectively as ternary are benefit to nosici and weight their ternu00e1rnu00edch hydrated amorphous carbon fe - ti to nosici is at an interval of 1 to 25%, and the resulting form think i'il justor granules.nosic is selected from the group tvorenu00e9 kremelinou, bentonite, lateritem, granular or pru00e1skovu00fdm activated carbon kremennu00fdm sand, porcelain grains, hrncu00edrskou clay, limestone, pumice stone against.manganicitu00fdm granular clay, sand, antracitem, zeolite, kaolin, cervenu00fdm mud (mud from aluminium production), and the magnetic fe.sub.3.n.o.sub.4.n dust... with...derived adsorbents are suitable for the obstacle of arsenic and selenium in drinking water and wastewater.
