The effects of arsenic pollution are serious and dangerous to human life. Especially long-term ingestion of contaminated water can cause various forms of cancer. Therefore, solving these problems raised by ...

The purpose of this paper was As (III) removal from simulated water by electrocoagulation (EC). The working conditions were: pH = 7, As (III) concentration 100 μg/L, and 0.01 M NaCl as supporting electrolyte. ...

A continuous adsorption study in a fixed-bed column was carried out by using IS:sand mixture as an adsorbent for the removal of As(III) from aqueous solution. The column experiments were conducted to study the effect of ...

Scientists found excessive arsenic concentrations is several underground waters in the world. In these areas, hundreds of thousands of people presented serious intoxications due to this element. Billions of people, especially ...
