Abstract (en)

[origin: WO0240975A1] The invention relates to a method for the determination of the concentration of polycarboxylates and/or polycarboxylic acids in a test water, whereby at least one reagent is added to the test water, which produces a turbidity with polycarboxylates and/or polycarboxylic acids, characterised in that the amount of the turbidity is compared with a scale of comparative grey values. Each comparative grey value corresponds to a concentration range for the polycarboxylates or polycarboxylic acids and from the comparative grey value closest to the amount of turbidity the content of polycarboxylates and/or polycarboxylic acids can be determined from the relationship of grey value to the concentration of polycarboxylates or polycarboxylic acids. The invention further relates to a set for carrying out said method.
