摘要：
A portable measurement system is used in this research. Our sensor has a short response time of 15 minutes, and the operation method is easy and convenient, suitable for home-care, as opposed to laboratory standard equipment like ICP-MS. This ion selective sensor has high sensitivity which is beyond ideal Nernst sensitivity, and a lower detection limit than that of ICP-MS. This Hg-ISMFET sensor can directly detect mercury ion from waste water which is from factory without any pre-treatment. In the future we can apply our sensor to detect mercury ion in food, Chinese medicine, and tea etc.
