Methods for precipitating iron and arsenic in the form of low soluble compounds, including iron oxide and arsenic, standardize confidence/As of 1-3.5 and pH of 1.5-4.5 to precipitate organic arsenic, and feed the precipitate into hydrogen energy conversion at 150-200 degrees Celsius for the purpose of Get the crystal scorpion.

摘要

Method for precipitating Arsenic and iron in the form of a poorly soluble Compound,That includes an oxidizing Solution containing Iron and Arsenic containing solution by means of an Oxidant, with a ratio of 1 - Faith - as a pH 3.5 and 1.5 - 4.5And send the precipitated a hydrothermal conversion to 150 - 200 degrees Celsius.
