Abstract:
Rapid heavy metal detector in site based on screen printing sensing technology with the principle of differential potential dissolution can be applied to the rapid detection of heavy metal lead in water samples,soil,food and agricultural products. The small-sized easy-to-carry instrument has the advantages of fast detection speed,high sensitivity,easy operation and low sample consumption. The results show that the relative standard deviation(RSD)is less than 2% and their coveries are from 98.49% to 101.58%. The detection results are consistent with the national standard method with excellent accuracy and precision. After the pre-treatment,the detection time of a single sample is about 3 minutes. The innovative instrument has excellent prospects for application in the field of trace heavy metal detection.
