Abstract

The invention relates to a process for water purification from hydrogen sulfide and sulfides and may be used in communal farms, fish breeding enterprises, public aquariums, autonomous filters, as well as for purification of ground waters.The process, according to the invention, consists in the use of modified diatomite, obtained by pre-treatment of diatomite with 24% NaOH solution, taken in a ratio of 1: (10…15), during 12 hours, after which the obtained suspension is heated in a water bath at the boiling temperature for 2 hours, it is added in excess a 30% MnCl2 solution and is maintained for 24 hours at the room temperature, the solid phase is filtered, immersed and maintained in a 24% NaOH solution for 24 hours at the room temperature, the supernatant is decanted and the solid phase is exposed to air, after which is washed with distilled water until the negative Cl- ions reaction, granulated and dried at the temperature of 105…200°C, at the same time the ratio of the adsorbent and purified water is 1: 800.
