Arsenic detection device reagent kit in water 【Scope of
Application】 This method is suitable for on-site rapid detection of
arsenic in water or urine. It also has certain reference value for the
detection of arsenic in food. 【Method Principle】 This method uses
reagents to reduce high valent arsenic to trivalent
arsenic. Trivalent arsenic combines with hydrogen in the gas production
tablet to form hydrogen arsenide. Hydrogen arsenide encounters mercury
bromide test paper to produce color spots, which are quantitatively compared
with the control color card. 【Method Steps】 Refer to video
operation 1) Take an appropriate amount of test
cotton and insert it into the hole at the bottom of the plug; 2) Take out one piece of test paper, gently
shake it dry in the air, place it on the circular hole on the upper end of
the plug, close the cover, and hear a clicking sound; 3) Take 50mL of the sample solution
into a triangular flask, add two spoons of arsenic detection reagent, add a
gas producing tablet, and immediately insert the prepared arsenic detection
stopper into the mouth of the triangular flask; 4) After 30 minutes, take out the
test strip and compare it with the control color card for quantification. 【Precautions】 1) This method is a rapid on-site
detection method, and accurate quantification should be based on the national
standard method. 2) Wear gloves and glasses during
operation. Avoid contact with children. 【Device
Configuration】 One bottle of arsenic testing paper, one bottle of arsenic
testing reagent, and one bottle of gas producing tablets, one bag of cotton
for testing, one medicine spoon, one triangular bottle, one folding stopper,
tweezers, and one control color card.
