摘要： Deposit formation in a drip irrigation system can be prevented with a treatment composition containing from 10 to 50 % by weight hydrogen peroxide, from 1 to 5 % by weight 1-hydroxyethylidene-1,1-diphosphonic acid and up to 0.5 ppm by weight arsenic, which is added to a water stream introduced into the drip irrigation system in an amount providing a concentration of from 5 to 100 ppm by weight hydrogen peroxide and from 0.5 to 10 ppm by weight 1-hydroxyethylidene-1,1-diphosphonic acid in the water stream.

摘要： A method for processing compositions, compositions obtained by such a process and methods of use are disclosed for forming a detachable and renewable protective coating which is substantially transparent. The inventive process compositions are produced by making a highly concentrated dispersion of hydrophobically modified silica particles in the presence of an optional, yet preferable, disilazane derivative under high shear conditions. These process compositions are intended to be further diluted to final treatment compositions, optionally while adding other functional ingredients.

摘要： Method for delignifying and bleaching pulp, comprising a first bleaching stage using hydrogen peroxide in the presence of a molybdate or a tungstate in an acidic aqueous mixture, followed by a second bleaching stage using hydrogen peroxide in an alkaline aqueous mixture, and followed by a third bleaching stage using hydrogen peroxide in the presence of a molybdate or a tungstate in an acidic aqueous mixture.

摘要： A method for reclaiming molybdate or tungstate from an aqueous solution, in which molybdate or tungstate from the aqueous solution is bound to a cationized inorganic carrier material which is insoluble in water at a pH value in the range between (2) and (6), the charged carrier material is separated, and the bound molybdate or tungstate is released back into aqueous solution at a pH value between (6) and (14). The cationized inorganic carrier material is, for example, a cationized layered silicate, preferably a bentonite which is ion-exchanged with a quaternary ammonium salt or a similar clay material. The method is suitable for reclaiming molybdate or tungstate during the delignification of cellulose using hydrogen peroxide, which is catalyzed using molybdate or tungstate. The reclaimed molybdate or tungstate can be returned into the delignification.
