抄録

A new coprecipitation method for the spectrophotometry of arsenic(III) and arsenic(V) in groundwater has been developed. Arsenic(III) and arsenic(V) were coprecipitated with thorium(IV) hydroxide from 1000 ml of groundwater at pH 9. The precipitate was centrifuged and then dissolved with hydrochloric acid. Arsenic(III) was spectrophotometrically determined by the usual silver diethylditiocarbamate (Ag-DDTC) method after generating the arsenic to arsine with sodium tetrahydroborate under masking the thorium with EDTA-NaF at pH 6. From another portion of the same groundwater, both arsenic(III) and arsenic(V) were determined by the Ag-DDTC method after reducing all the arsenic to arsine with sodium tetrahydroborate at pH less than 1 in the presence of the EDTA-NaF. The concentration of arsenic(V) was obtained by subtracting that of arsenic(III) from the total for arsenic.
