    摘要： The invention relates to a particular polymer which is derived from a copolymer polysaccharide formed by a main chain comprising similar or different anhydrohexose units and branches including at least one neutral or anionic anhydropentose and/or anhydrohexose unit. Moreover, the invention relates to the use of said polymer in the treatment of aqueous media, in particular the treatment of aqueous effluents containing heavy metals, the treatment of waste water, drinking water and for sludge conditioning. Said derivative polymer comprises one or more units bearing an oxime function at least at position C2.

    摘要： The invention provides the use of a water-soluble biocide as an uncoupling agent at an effective amount to control bacterial biomass in an aqueous system. The invention also provides a method for controlling the growth of bacterial biomass in an aqueous system. The method comprises adding to, or contacting with, the aqueous system an effective amount of an uncoupling agent which is a water-soluble biocide. In a preferred embodiment the method comprises contacting an effective amount of an uncoupling agent which is a water-soluble biocide directly with the bacterial biomass in an aqueous system.

    摘要： The present invention concerns a process for the preparation of a rare-earth sulphide characterized in that a rare-earth halide is brought into the presence of an alkaline or aluminum halide and heated in the presence of hydrogen sulphide at a temperature which is sufficient to volatilize the halides. More particularly, the halide is a chloride, the rare-earth is cerium and the alkali is sodium.
