摘要

通过热和氧化过程对泥炭进行物理化学改性，以获得新的、廉价的和活性的材料，用于不同类型的水的净化。在改性过程中，表面形成了希洛夫型化合物。研究了物理化学改性泥炭(PCMP)在h2s和胶体硫水溶液中的批处理吸附性能和除臭性能。此外，还测试了PCMP去除污染水中有害成分As(V)的效果。污染物结合的可能机制包括相互作用，它导致加合物和包合物的形成。对这些过程进行了详细的阐述。结果表明，所得材料可用于去除不同类型水中的硫化物、胶体硫和As(V)。

Physicochemically modified peat by thermal and oxidation processes as an active material for purification of wastewaters from certain hazardous pollutants

The physicochemical modification of peat through thermal and oxidation processes was carried out, in order to obtain new, inexpensive and active material for purification of different types of waters. During the modification, surface chemical compounds of Shilov type were formed. Batch adsorption properties and suitability of physicochemically modified peat (PCMP) for odor removal were tested in aqueous solutions of H 2 S and colloidal sulphur. Additionally, PCMP was tested in the removal of As(V) which is hazardous ingredient in contaminated waters. Possible mechanisms of pollutants binding include interactions, which lead to formation of adducts and clathrates. All these processes are elucidated in detail. The results showed that the obtained material can be used for the removal of sulphide, colloidal sulphur and As(V) from different types of waters.
