Abstract
Способ получения сорбента для очистки воды путем проведения химической обработки материала в три стадии, включая обработку раствором соли двухвалентного марганца и доведение рН среды от 8 до 12, с последующей сушкой обработанного материала, отличающийся тем, что в качестве материала используют базальтовые волокна, которые предварительно измельчают в водной среде при перемешивании до размеров от 1 до 25 мм и химически активируют с помощью одной из ряда неорганических кислот: соляной, серной или азотной, а три стадии химической обработки материала последовательно осуществляют солью двухвалентного марганца концентрацией, равной от 0,5 до 2%, доведением рН среды от 8 до 12 и добавлением пероксида водорода концентрацией, равной от 0,15 до 2%, после чего проводят сушку обработанного материала при температуре от 120 до 200°С с дальнейшей термической обработкой при температуре от 250 до 350°С в течение 0,5-1 ч.A method of producing a sorbent for water purification by carrying out chemical treatment of the material in three stages, including treatment with a salt solution of divalent manganese and adjusting the pH of the medium from 8 to 12, followed by drying of the treated material, characterized in that basalt fibers are used as the material, which are pre-ground in an aqueous medium with stirring to sizes from 1 to 25 mm and chemically activated using one of a number of inorganic acids: hydrochloric, sulfuric or nitric, and the three stages of chemical processing of the mat The series is successively carried out with a divalent manganese salt with a concentration of from 0.5 to 2%, adjusting the pH of the medium from 8 to 12 and adding hydrogen peroxide with a concentration of from 0.15 to 2%, after which the treated material is dried at a temperature of from 120 to 200 ° C with further heat treatment at a temperature of from 250 to 350 ° C for 0.5-1 hours
