摘要：Arsenic is a naturally occurring element in the Earth crust that is usually found combined with other elements. Studies have reported that inhalation of arsenic results in an increased risk of lung cancer. Arsenic is released to the environment from a variety of natural and anthropogenic sources. Due to these varieties of pollution sources with arsenic, in the present paper it was studied the possibilities of arsenic removal from water through coagulation-precipitation method using the Jar-Test method. As coagulation-precipitation agents were used Fe²⁺, Fe³⁺ and Al³⁺. From the experimental data resulted that the optimum conditions of arsenic removal from water are: reaction mass pH = 9 and a coagulation-precipitation agent dose of 200 mg/L; the best coagulation-precipitation agent is Fe²⁺.
