Background and Objective: Acid Black 1 dye
due to the presence of benzene ring, toxicity,
mutagenicity, carcinogenicity and non-degradability is one of the major dangers
for human health and environment especially aquatic life. Hence, the removal of
these compounds from polluted water and wastewater has been considered. This study has
been investigated the removal of
acid black1 azo dye from aqueous solution in the presence of SiO2, CuSO4 and Na2SO4.
Materials and Methods: In this experimental
study the treatability of effluent polluted with reactive acid black 1 dye was
investigated by using sonochemical oxidation in a reactor. The sample with the desired concentrations
of dye (200-400 mg/L) in pH= 3-11 was prepared, also the required
concentrations of silica, copper sulfate and sodium sulfate (25 to 100 mg/L)
and S2O82- (1 to 10 mM/L) were flowed into the
reactor intermittently. Ferrous sulfate as a source of ion (1 to 10 mM/L) was
used.
Results: The results
have showed that 100% of the dye after 45 min at pH 3, 7.5 mM/L persulfate and
concentration of 100 mg/ L in presence of 3 additives was removed. The dye
removal in above condition decreased to 89.89% without the presence of
additives. Also, the results showed that increasing the concentration of
persulfate more than 10 mM/L no effect of removal of efficiency and the removal
of the 64.56 percent decline.
Conclusion:The
findings showed the combined process of ultrasonic and persulfate with the presence
of 3 additives in optimal conditions of operation can be used as an acceptable
option in the removal of dye in
various industrial wastewater.
