摘要： A phosphonium compound embedded in a matrix substrate wherein the phosphonium compound is selected from a group consisting of tris(hydroxyorgano)phosphine (THP), a THP+ salt (tetrakis(hydroxyorgano)phosphonium salt) or a condensate of THP and a nitrogen containing compound. The compound may be used to reduce the number of microorganisms in industrial systems and may also be used to reduce iron carbonate or iron, lead and zinc scale deposits.

摘要： A method for treating an inorganic slurry to preserve the slurry against bacterial contamination, including (I) providing a slurry in a substantially homogeneous phase, and then (II) adding to the slurry an effective amount of a composition containing: (a) a tetrakis(hydroxyorgano)phosphonium salt selected from the group consisting of tetrakis (hydroxymethyl) phosphonium sulphate, tetrakis (hydroxymethyl) phosphonium chloride, tetrakis (hydroxymethyl) phosphonium phosphate, tetrakis (hydroxymethyl) phosphonium nitrate and tetrakis (hydroxymethyl) phosphonium oxalate; and (b) a dispersant selected from the group consisting of (i) a phosphonated compound containing at least one tertiary nitrogen atom and (ii) a homopolymer of an unsaturated acid; and (III) preserving the slurry against bacterial contamination, whilst avoiding instantaneous heterogeneous thickening of the slurry due to the tetrakis (hydroxyorgano) phosphonium salt.
