dc.description.abstract | The synthesis and application of sodium trithiocarbonate (Na2CS3) for the treatment of real
galvanic wastewater in order to remove heavy metals (Cu, Cd and Zn) was investigated. A Central
Composite Design/Response Surface Methodology (CCD/RSM) was employed to optimize the
removal of heavy metals from industrial wastewater. Adequacy of approximated data was verified
using Analysis of Variance (ANOVA). The calculated coefficients of determination (R2 and R2
adj) were
0.9119 and 0.8532, respectively. Application of Na2CS3 conjugated with CCD/RSM allowed Cu, Cd
and Zn levels to be decreased and, as a consequence, åCu,Cd,Zn decreased by 99.80%, 97.78%, 99.78%,
and 99.69%, respectively, by using Na2CS3 at 533 mg/L and pH 9.7, within 23 min. Implementation
of conventional metal precipitation reagents (NaOH, Ca(OH)2 and CaO) at pH 11 within 23 min
only decreased åCu,Cd,Zn by 90.84%, 93.97% and 93.71%, respectively. Rotifer Brachionus plicatilis
was used to conduct the assessment of wastewater toxicity. Following the application of Na2CS3,
after 60 min the mortality of B. plicatilis was reduced from 90% to 25%. Engagement of Na2CS3
under optimal conditions caused the precipitation of heavy metals from the polluted wastewater and
significantly decreased wastewater toxicity. In summary, Na2CS3 can be used as an effective heavy
metal precipitating agent, especially for Cu, Cd and Zn. | pl_PL |
