Below, we will introduce the solution preparation method of the multi-parameter boiler water quality detector.
Standard solution, also known as standard substance, is a simulated natural freshwater component matrix, using a special process, accurately formulated in a specified environment.Its concentration of nitrate nitrogen is known. Users can prepare it by purchase or as required. Standard solutions mainly have the following uses:
(1) Calibrate the curve of the water quality tester;
(2) Check the accuracy of the multi-parameter water quality analyzer;
(3) Confirm and review the analysis data of the experimenter;
(4) Quality control of the whole measurement process of the experiment.
First, the preparation method of the standard solution (reserve solution):
Weigh the potassium nitrate before drying in l05~110℃ for 4 hours and cooling (KNO3)0.7218g all dissolved in ammonia water, transfer to 1000 mL volumetric flask, dilute with water to the line, shake well, the nitrate nitrogen value of the solution is 100 mg/L. Add 2ml of trichloromethane (CHCl3) as protective agent for at least 6 months.
Second, the standard use of liquid preparation method:
Using the multi-parameter water quality analyzer test needs to absorb 20ml of the above standard reserve solution in 100ml volumetric flask, dilute to the line with ammonia water, mix well, the nitrate nitrogen concentration of this solution is 20 mg/L, and should be prepared at any time.
The solution preparation method of multi-parameter boiler water quality detector is the above step, for the determination of boiler water quality, according to the relevant provisions in "GB / T 1576-2008 Industrial Boiler Water Quality", generally mainly have turbidity meter, dissolved oxygen meter, oil meter, TDS tester, phosphate tester, chloride tester, tester, alkalinity tester and sulfite tester, etc.The ERUN-ST series produced by Erun Environmental Protection has customized a series of testing instruments for boiler water quality testing parameters. If you need specific information of boiler water testing, you can directly contact customer service directly. The customer service team of Yingrun Environmental Protection Group will serve you at any time.
