Definition and scope of application
This method uses dimethylglyoxime spectrophotometry to determine trace nickel in water.
This method is applicable to surface water, groundwater, domestic sewage and industrial wastewater
When the volume of water sample is 1ml and a 10 mm diameter colorimetric tube is used, the detection limit of this method is 0.01mg/l, the detection limit is 0.04mg/l, and the detection limit is 1.0mg/l.
The determination method of Trace Nickel developed by Shenzhen Changhong Technology Co., Ltd. (hereinafter referred to as "shenchanghong") is simple, rapid, economical and accurate. Shenchanghong can provide a complete analysis scheme for the determination method of trace nickel, and users do not need to prepare trace nickel reagents by themselves. The scheme includes trace nickel analyzer and matching trace nickel reagent. Trace nickel reagent is used together with trace nickel analyzer. The analytical procedure is simple and convenient, which meets the requirements of national industry standards.
● no need to prepare trace nickel reagent: the reagent prepared by a certain proportion of the chemical components required for Trace Nickel analysis can greatly save the preparation time of Trace Nickel reagent;
● time saving: the whole analysis process, including water sampling, reagent addition, colorimetric determination and other steps, takes much less time than traditional methods;
● simple operation and easy to learn: the operation guide with pictures and texts is convenient for mastering the copper analysis method in a short time.
Analysis steps of Trace Nickel in shenchanghong:
(1) Preparation of Trace Nickel reagent and water sample
Put the reagent required for Trace Nickel analysis into each trace nickel tube, add a proper amount of water sample according to the instructions, and then tighten the cap.
(2) Determination of Trace Nickel by colorimetry
Shenchanghong's trace nickel determinator (chni-120 / pchni-120 / mulp-8a / C / D / pmulp-4c / 8C / mulp-4b / gw-2000 / chmm-900, etc.) selects the corresponding trace nickel test program in the main menu, does not need to re-establish the standard curve, only needs to put the trace nickel reagent test tube into the instrument to read the trace nickel value expressed in concentration units, and can save the record results.
