FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and chemical engineering. Water undergoes photodecontamination using radiation in the visible range in the presence of oxygen and a sensitising agent. The sensitising agent used is a heterogeneous sensitising agent of general formula:
,
where R=Cl, NHCH2CH2SO3Na, NR3 +X-, N+(CH3)2CH2CH2OH X-, Py+X-; X is an anion, n=4-9; R1=H, SPh; M=Zn, Al(L), Ga(L), Si(L2); L=Cl, OH.
EFFECT: invention enables decontamination of water from bacteriological pollution.
