Analyses environmental, reducing agent

Redox titrations find numerous applications in environmental analysis. Iodo-metric titration involving the reaction of iodine with a reducing agent such as thiosulfate or phenylarsine oxide of known strength is a typical example of a redox titration. This method is discussed separately in the next section. Another example of redox titration is the determination of sulfite, (S032-) using ferric ammonium sulfate, [NH4Fe(S04)2]. 

AR 50-6 also defines requirements for management of RCWM. The regulation specifies that emergency on-site destruction of chemical munitions may be considered an option to reduce risk and that non-emergency on-site destruction is subject to CERCLA or RCRA. Also, AR 50-6 indicates that soil suspected of contamination by chemical agents or industrial chemicals is presumed hazardous until confirmed otherwise by laboratory analysis and is required to be managed in accordance with environmental laws and regulations. 

Capillary column GC-MS/MS offers the analyst the potential for highly specific, sensitive detection of chemical warfare agents as this technique significantly reduces the chemical noise associated with complex biological or environmental sample extracts. The specificity of product scanning with moderate sector resolution, as well as the specificity of ammonia Cl, was demonstrated with a hybrid tandem mass spectrometer during analysis of painted panel samples circulated during an international round robin verification exercise.
