General description

The test measures nickel(II) ions in groundwater and surface water, drinking water, industrial water and wastewater.

Method: colorimetric with color-disk comparator 0.5 - 1.0 - 1.5 - 2 - 3 - 4 - 6 - 8 - 10 mg/l Ni MQuant^®

The MQuant^® Nickel test (formally MColortest^®) measures nickel(II) ions in Groundwater and surface water Drinking water Industrial water Wastewater and percolating water Electroplating wastewaterThis test is not suited for seawater.MethodNickel(II) ions are oxidized by iodine and then transformed with dimethylglyoxime in an ammoniacal solution into a red-brown complex. The nickel concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation. The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments. Using the refill pack 1.18461 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
