A novel automated framework for water impurity detection

Proposed work involves the development of algorithm and computer simulation of a Hexagonal Ring Structure-based photonic sensor for the detection of harmful water impurities. An optical sensor ring structure is used to detect impurities such as Lead, DDT, Chlorine, PCB, Arsenic, Mercury, Fluoride, Aluminum. A comparison between two types of sensing structures is investigated for different water impurities. It is observed that the designed optical sensor is giving more amplitude variation for e. g 1.7 for lead impurities as compared to MZI based optical sensor with an output value of 0.4 and gives fast appropriate output. A sensitivity of 350 nm/RIU and Q factor of 3453 is obtained for the designed sensing sensor. The result has shown a feasible fabrication possibility in the future for sensing applications. Work carried having tremendous potential application in the detection of impurities in the drinking water application.
