Product Description

Product Description

Water quality heavy metal analyzer Water quality heavy metal detector water metal detector 
1. Product features

The portable water quality heavy metal rapid detector adopts electrochemical rapid detection method---anodic stripping voltammetry, combined with the national standard method---photometric colorimetry, which can be applied to on-site emergency detection (such as emergency monitoring of water environment pollution accidents). It is applied to the detection and analysis of heavy metals in laboratories. At present, the main customer groups are environmental protection bureaus, water affairs bureaus, monitoring stations, water companies and CDCs, etc., which can be applied to surface water, groundwater, seawater, industrial wastewater and drinking water or Monitoring of other environmental water bodies.

2.Product Parameter

 

project

 

 

The main technical parameters

 

 

Measurement parameters

 

 

More than ten heavy metal parameters such as copper, cadmium, lead, zinc, arsenic, mercury, thallium, manganese, antimony, nickel, etc. (more parameters can be extended to measure) 

 

 

 

scope of test

 

 

Stripping voltammetry: 0.1μg/L~tens of mg/L

Colorimetric method: 0.01mg/L~5mg/L (developed copper, chromium, nickel, lead, zinc, iron, cobalt, manganese, etc.)

Note: The detection range of different elements is slightly different

 

 

Repeatability

 

 

RSD≤2% (calculated as Cd 50μg/L) 

 

Indication error 

 

 

≤±10%

 

The detection limit

 

 

≤0.5μg/L

 

Instrument selection:

YSHM-200W/YSHM-200M

YSHM-200M is equipped with a colorimetric module on the basis of YSHM-200W, which can be extended to measure hexavalent chromium, nickel, manganese and other indicators. It can meet the on-site rapid detection of heavy metals in water quality by environmental monitoring institutions at all levels, academy of environmental sciences, universities, water plants, public security inspection departments, enterprises, etc.

 

Application case: Field test of surface water

Water sample matrix: take some actual water samples from the bank of a certain river

Test method: Take the actual water sample as the matrix, add a certain amount of lead, cadmium, mercury, and hexavalent chromium standard solution (the concentration of each metal ion is 50ug/L), and use the instrument ASV (anode stripping, corresponding measurement of lead, The cadmium, mercury) module and the colorimetric module (corresponding to the measurement of hexavalent chromium) were measured separately, and the actual water sample was tested for the recovery rate of standard addition.

Before adding standard After adding standard Recovery value Standard recovery rate (%) 
1 lead 0.02 50.3 50.2 100.4
2 cadmium 0.05 49.6 49.5 99.0

4 HG 0.17 48.9 48.7 97.4
5 Hexavalent chromium 0.03 49.8 49.7 99.4

 

For the above spiked samples (100ug/L), lead and cadmium were determined by plasma mass spectrometry, zinc by flame atomic absorption method, mercury by atomic fluorescence method, and hexavalent chromium by spectrophotometer. The results are as follows:

5 Hexavalent chromium 98.5 98.5 102.8 102.8


Conclusion: The portable water quality heavy metal analyzer has the characteristics of small size, convenient carrying, simple pretreatment, low detection limit, high detection accuracy, and fast detection speed. The test results have a good correlation with laboratory instrument methods, which can be very Convenience.
