| description | The invention relates to a measurement technique of heavy metal copper, in particular to a reagent used for measuring the copper in water and a preparation method thereof. According to weight parts, the reagent consists of 20-80 portions of chromogenic reagent, 50-200 portions of reducing agent, 100-700 portions of acidity regulator and 50-120 portions of masking agent; all compositions are sufficiently ground and uniformly mixed; and subsequently, the mixture is separately loaded in capsules with the quantity of 100-150mg per capsule and hermetically and dryly stored. The preparation method can simplify the analysis procedures, saves the operations such as weighing, liquid compounding and the like, is convenient and quick, reduces personal errors and can obtain exact results when the operations are carried out by non-analysis personnel. The reagent is solid powder capsule, and avoids instability of the liquid reagent; the hermetical shelf life under normal temperature is more than 6 months; furthermore, when |
