摘要
A method of detecting arsenic comprising acidifying at least one sample comprising a known arsenic concentration, reducing arsenic in the sample having the known arsenic concentration to arsine, contacting the arsine in the sample having the known arsenic concentration with a reagent to produce a chemiluminescent emission, measuring the intensity of chemiluminescent emission produced by the sample having the known arsenic concentration, acidifying at least one sample comprising an unknown arsenic concentration, reducing arsenic in the sample having the unknown arsenic concentration to arsine, contacting the arsine in the sample having the unknown arsenic concentration with a photoagent to produce a chemiluminescent emission, measuring the intensity of chemiluminescence emission produced by the sample having the unknown arsenic concentration, and determining the arsenic content in the sample having an unknown arsenic concentration by comparing the intensity of chemiluminescent emission of the sample comprising a known arsenic concentration to the chemiluminescent emission of the sample comprising an unknown arsenic concentration, wherein the arsine is not subjected to a low-temperature trap prior to the reaction with a photoagent.
