研究了在中性介质中用无机物分离地下水中砷的分析方法。分离过程包括在中性介质中，砷在水合二氧化锰上的定量保留。分离过程的有效性已被检查的标准加入法和放射性示踪剂的研究。中子活化分析（NAA）是一种强有力的测量技术，已被用于砷的定量测定。
An analytical methodology has been developed for the separation of arsenic from ground water using inorganic material in neutral medium. The separation procedure involves the quantitative retention of arsenic on hydrated manganese dioxide, in neutral medium. The validity of the separation procedure has been checked by a standard addition method and radiotracer studies. Neutron activation analysis (NAA), a powerful measurement technique, has been used for the quantitative determination of arsenic.
