Abstract—At present, arsenic in the environment has caused content than other methods , its precision and accuracy are
obviously global health problem, an effective monitoring method very high and input costs are low, especially suitable for
for measuring the content of arsenic in surface water is urgent. analysis of large quantities of surface arsenic content in water
In this paper, the silver diethyldithiocarbamate and wastewater.
spectrophotometric method was used to measure arsenic content
in surface water. It was concluded that the related coefficient for Fen River Reservoir and Fen River Reservoir II in Taiyuan
standard curve was , the detection limits was / L, mainly have functions for providing clean water for industries
the relative error was below %, the recovery efficiency of and residents in Taiyuan. The silver diethyldithiocarbamate
standard adding material was from 90 % to 110 %, which was spectrophoto
