Abstract
A sorbent particulate material, such as a metal hydroxide-coated sawdust, is made by passing a direct electric current between an anode of a metal capable of forming a flocculent hydroxide and a cathode in a turbulent electrolyte containing the dispersed particulate material, so as to form a metal hydroxide and deposit it on such material. Also described are filters made from the sorbent particulate material and processes of filtering or otherwise removing undesired components from liquid media by means of such product.
Claims12
A process for the manufacture of a sorbent particulate material, substantially all of which is of a mean particle diameter of about 0.1 to 10 mm., which comprises passing an electric current between an anode of a metal capable of forming a flocculent hydroxide, which is selected from those of Groups IIA, VIB, VIIB, VIII, IB, IIB, IIIA, IVA and VA and alloys thereof, and a cathode in a turbulent electrolyte containing dispersed particulate material of the given size, to form a metal hydroxide and deposit it on the dispersed particulate material.
