Abstract
Abstract A method for the purification of fluids such as water, aqueous fluids and liquid fuels, comprises contacting said fluids with a solid material body of a novel alloy which comprises 50 to 60% copper, 20 to 28% zinc, 0.5 to 8% nickel, 0.005 to 2.5% aluminum, 7 to 15% manganese, and 1.3 to 4.5% tin, based on the total weight of the alloy.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
In a method for the purification of a fluid selected from the group consisting of water, aqueous fluids and liquid fuels, which comprises the steps of providing a hollow chamber having inlet and outlet ports, providing a solid material body within said chamber, said solid material body being made of a metal alloy, passing said fluid through said chamber for contacting said fluid with said solid material body, and recovering purified fluid from said chamber, the improvement wherein said solid material body comprises a metallic alloy which comprises 50 to 60% copper, 20 to 28% zinc, 0.5 to 8% nickel, 0.005 to 2.5% aluminum, 7 to 15% manganese, and 1.3 to 4.5% tin, based on the total weight of the alloy.
