Low Loading Gold Vapor Deposited Electrode For High Sensitivity As (Iii) Detection, Tybur Casuse
Civil Engineering ETDs
The objective of this thesis is to develop a method for detection of arsenite, As (III), using a thin film of gold (Au) vapor deposited onto carbon paper as an electrode. Currently, availability of drinking water arsenic (As) concentration information for rural communities is diminished due to high cost per sample analysis and limited access to analytical laboratories which can accurately determine concentrations near the 10 maximum contaminant level (MCL) set by the World Health Organization (WHO) and the US Environmental Protection Agency (EPA). The use of a minimal amount of gold aids in decreasing the cost of an electrode. …
