Paper Abstract

Monitoring of water quality is essential to modern life. Not only is it a major factor in safeguarding public health, high quality freshwater is also a key input in agriculture and many industrial process. A preliminary prototype for hydrogen peroxide content in water is setup and introduced. Based on the detection of beam deviation due to the refractive index changes of the aqueous hydrogen peroxide solution, hydrogen peroxide content can be measured by a position-sensitive detector. Measurement principle is theoretically described. Experimental results indicate the feasibility of the developed system. Not like intensity-modulated refractive index sensor which necessitates a stable light source, this sensor exploits the beam deviation due to optical refraction at the receiving end face of the measurement cell, which is caused by changes in refractive index with different hydrogen peroxide content in water. Hydrogen peroxide content measurement resolution can reach about 0.01% within the measurement range from distilled water to hydrogen peroxide content of 30%.
