The nanoparticles of gold and cadmium tellurium quantum dot (CdTe QD) are effective systems for the detection and quantitative removal of chlorpyrifos which is a commonly used pesticide found in surface water of developing nations. Gold nanoparticles coated with citrate changes its color from pink to purple in the presence of chlorpyrifos. Unique CdTe QDs were developed and functionalized by using glucose oxidase for detection of chlorpyrifos. Change in absorbance related to the change in H2O2 concentration. In the solution phase, chlorpyrifos adsorb onto the CdTe QDs surface. During this prolonged interaction, change in color takes place and adsorbed chlorpyrifos becomes precipitated. Thus complete removal of this chlorpyrifos occurs when contaminated water is passed over different CdTe QDs supported on some surface such as alumina. We believe that this method has great potential in the purification of drinking water using gold and CdTe QD nanoparticles.
