Definition and scope of application
This method uses Chromazurol S spectrophotometry to determine aluminum.
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 0.40mg/l.
principle
In the range of pH = 7.5-8.6, aluminum reacts with chrome azurol in the presence of CPB to form a blue-green quaternary micelle, which is determined by spectrophotometry.
The aluminum test method developed by Shenzhen Changhong 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 aluminum test method, and users do not need to prepare their own aluminum reagents. This project includes aluminum analyzer, aluminum reagent and so on. Aluminum Reagent and aluminum 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 aluminum reagent: the reagent prepared by a certain proportion of chemical components required for aluminum analysis can greatly save the preparation time of aluminum 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 aluminum in a short time.
Analysis steps of shenchanghong aluminum
(1) Preparation of Aluminum Reagent and water sample
Put the reagent required for aluminum analysis into each colorimetric tube for aluminum test, add a proper amount of water sample according to the instructions, and then tighten the bottle cap.
(2) Aluminium colorimetric determination
Shenchanghong's aluminum tester (chal-130 / pchal-130 / mulp-8a / C / D / pmulp-4c / 8C / mulp -, etc.) selects the corresponding aluminum test program in the main menu. Without re establishing the standard curve, it is only necessary to put the aluminum reagent test tube into the instrument to read out the aluminum value expressed in concentration units and save the record results.
