Method for removing manganese from water

Effluent treatment

A method for removing suspended impurities and colored substances from water which is hard and/or has a pH in excess of 5 which comprises contacting the water at its natural pH with a coagulant/adsorbent which comprises a finely divided particulate mineral material, the individual particles of which have a thin hydroxylated surface layer having a positive zeta potential at the adsorption pH, and separating the thus treated water from the coagulant/adsorbent.

Method of removing impurities from hard waters or waters with

Processes for making copolymers comprising treating a reaction mixture of a monomer and a substrate comprising ferromagnetic material located in a polymeric matrix so as to polymerize the monomer in a manner that it forms a polymeric shell grafted on to and surrounding the substrate, the polymerization of the monomer being initiated by adding the components of a redox system sequentially to the reaction mixture.

Ion exchange processes and products

A process for making dimensionally-stable composite materials comprising adsorbents and magnetic particles embedded in a porous matrix of organic polymeric materials. The magnetic particles enable the composites to be easily and rapidly removed from treated solutions after the adsorption stage is complete.

Process for making composite magnetic material

A selective adsorbent for the separation of organic material from solution comprises adsorbent particles and magnetic particles embedded in a porous matrix of organic polymeric material, the porosity of the matrix being selected so as to allow only molecules of up to a certain order of molecular weight to enter into the interstitial structure of the matrix whereby the composite material functions selectively to adsorb dissolved materials from solution. The adsorbent is useful, inter alia, in the food processing industry where trace quantities of materials need to be separated from complex mixtures.
