Resumo: | ||||||||
In Brazil, the use of energy produced by power plant
generators is in expansion. Power plants use large
quantities of water and chemical products that after use
end up in effluents. Hydrazine is used in water systems for
corrosion control, because of its excelents oxygen
scavenging capacity. The present work was conducted to
study the treatment of effluents containing hydrazine,
under a technological approach, with the purpose of
contributing to a systematic of effluents control in power
stations. The process studied in this work was the
decomposition of hydrazine with hydrogen peroxid in
presence catalyst cooper íon. The experiments were made in
laboratory scale, using synthetic effluents with initial
concentration of hydrazine at the levels 10 and 100 mg/L,
with initial pH values 7 and 9,5, temperature fixed at
220C, with addition of st oichiometric amounts of hydrogen
peroxide, with and without addition of cooper ion catalyst.
It was conclued that the process its viable for reduction
of hydrazine concentration in effluents with pH 9,5, below
to levels under legislation (1mg/L), using stoichiometric
amounts of hydrogen peroxide together with 1 mg/L of cooper
ion, in times less that 30 minutes and ambient temperature.
Therefore this work showed that the process is adequate in
satisfying the Brazilian legislation for discharge of
effluents into water bodies according to regulation
