Abstract:
The sorption properties of polymers with a polyconjugated chain structure (polyaniline and polypyrrole) are considered. The molecular mechanism of sorption by these polymers of various compounds such as heavy metal ions, toxic organic compounds and micropathogens, which are the most hazardous and stubborn contaminants in water, is discussed. The use of such sorbents to purify water from micropathogens, including bacteria and viruses, is addressed for the first time. The adsorption capacity of polyconjugated polymers for these types of contaminants, the efficiency of water treatment by these sorbents and characteristics of the currently used sorbents are analyzed. The applicability of polyaniline and polypyrrole and composites based on them as high-performance versatile sorbents for water treatment is discussed, taking into account the sorbent properties such as high stability, lack of solubility, lack of toxicity and ability to be regenerated and reused.
The bibliography includes 194 references.
