Sorption properties of composite peat mineral materials
Abstract
The water-physical and sorption properties of carbonate-containing minerals (chalk, dolomite flour, tripoli) as components of composite sorption materials based on peat were studied.
Samples of granular composite sorption materials based on peat and the above carbonate-containing minerals containing the latter of 25 and 50 % were obtained. It has been shown that the absorption of ammonia in the molded compositions is reduced, and the addition of calcium carbonate (chalk) to the composition in an amount of 25 % has a lesser effect on the amount of absorbed ammonia compared to the same addition of dolomite flour and tripoli. The water absorption of composites is slightly reduced compared to granulated peat.
It has been established that the introduction of dolomite flour and tripoli in an amount of 25 % increases the abrasion strength of composites, which is associated with structure formation processes through the interaction of peat functional groups with metal ions.
The kinetics of ammonia and water adsorption in gas phase by peat and peat-mineral sorbents has been studied. It has been established that ammonia is absorbed most intensively during the first two to three days, then the intensity of absorption decreases. The composition was optimized and the formulation of peat-mineral sorbent was developed.
