2020-03-03 09:54:11        0

  Definition and scope of application

  This method uses dithizone spectrophotometry to determine zinc.

  This method is applicable to surface water, groundwater, domestic sewage and industrial wastewater

  When the volume of water sample is 5ml and a 10 mm diameter colorimetric tube is used, the detection limit of this method is 0.1mg/l, the detection limit is 0.4mg/l, and the detection limit is 5.0mg/l.


  In the solution with pH = 7.5-8.6, zinc reagent and zinc ion form a blue complex, which is determined by spectrophotometry.

  The zinc test method developed by Shenzhen Changhong science and Technology Co., Ltd. (hereinafter referred to as shenchanghong) is simple, fast and economic in operation, and the test results are accurate and reliable. Shenchanghong can provide a complete analysis scheme of the zinc test method, and users do not need to prepare their own zinc reagents. The project includes zinc analyzer, zinc reagent and so on. Zinc reagent and zinc analyzer are used together, the analysis steps are simple and convenient, and meet the requirements of national industry standards.

  Product characteristics

  ● no need to prepare zinc reagent: the reagent prepared by a certain proportion of chemical components required for zinc analysis can greatly save the preparation time of zinc reagent;

  ● time saving: the whole analysis process, including water sampling, 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 analysis method of zinc in a short time.

  Analysis steps of shenchanghong zinc

  (1) Preparation of zinc reagent and water sample

  Put the reagents needed for zinc analysis into each colorimetric tube for cadmium test, add a proper amount of water sample according to the instructions, and then tighten the bottle cap.

  (2) Zinc colorimetric determination

  Shenchanghong's Zinc tester (chzn-180 / pchzn-180 / mulp-8a / C / D / pmulp-4c / 8C / mulp-4b / gw-2000 / chmm-900, etc.) selects the corresponding zinc test program in the main menu. It does not need to re-establish the standard curve, just put the zinc reagent test tube in the instrument to read the zinc value expressed in concentration units, and save the record results.
