Mechanism of Ammonia Immobilization by Peat and Obtaining of Peat-Based Sorbent
Complex utilization of renewable sources of organic matter is of great interest at the present time. Fields of manufactured or worked-out products' application are exceedingly diverse. One important aspect is to obtain sorbents based on plant porous matrices. Among the renewable plant resources, peat is considered to be a unique natural formation, which combines properties of the plants and its biodegradation products due to the specific hydrological conditions. Peat is characterized by great diversity and lability of organic compounds. Assignment of the essential role of the peat polymer matrix, formed by aromatic polyconjugation systems, served as the basis for the development of environment-friendly technology of peat treatment by weak acids which does not destroy the structure of peat organic matter. Extra equivalent sorption of ammonia by peat is based on energetically favorable formation of cross-linking hydrogen and donor-acceptor bonding by peat molecules with polyconjugation fragments.
