“…On large 52(4) 2017 310 scale H 2 S is removed by aeration by employing complex packed tower aerators, simple air diffusers and mechanical aeration devices in wastewater treatment plants (Murugananthan et al, 2004) (Murugananthan et al, 2004;Edwards et al, 2011;Tomar and Abdullah, 1994;Millero et al, 1989). Manganese (IV) Oxide (MnO 2 ) for oxidation of sulfides in wastewater has also been reported (Valeika et al, 2006).…”

In batch mode, the adsorption characteristics of S 2¯i ons on Lagenaria siceraria mesocarp, pedicle and peel as raw materials have been studied in comparison to remove sulfide ions from tanneries waste water, under various parameters such as adsorbent dosage, contact time, agitation speed and pH. Maximum removal efficiency (70.96%) was observed on L. Siceraria peel followed by pedicle (51.58%) and mesocarp (29.57%) for adsorbent dosage of 0.10 g/L peel for 50 ml solution of sulfide (20 mg/L). The adsorption process was rapid, and it reached equilibrium in early 20-35 min for all adsorbents. Freundlich and Langmuir adsorption isotherms were employed for mathematical description of the adsorption equilibrium and to explain mechanism of adsorption.The maximum amounts of sulfide ions adsorbed, as evaluated by Langmuir isotherm, was 1.0436 mg/g of LS pedicle, 0.886 mg/g of peel and 0.843 mg/g of pedicle. The adsorption process conforms well to a pseudo second order kinetic model with best adsorption results at pH 8.

“…Several oxidants, such as molecular oxygen [5], hydrogen peroxide [6], hypochlorites, chlorine and KMnO 4 [7] have been tried to eliminate H 2 S from wastewater. Selective electrochemical oxidation of sulfide compounds in the presence of organic matter, Mn 2+ and Cr 3+ was also studied by Rajalo and Petrovskaya [8].…”

Metal–sulfide complexation in seawater

The conditional stability constants of metal-sulfide complexes were determined in pH 8 seawater at various salinities, by Ž . flow-analysis with detection by cathodic stripping voltammetry FA-CSV . Two methods were used. The first method was titration of the sulfide by metal with detection of the free sulfide by FA-CSV. The titrant metals were Ag q , Cd 2q , Co 2q , 2q 2q 2q 2q 3q 3q Ž . Fe , Mn , Pb , Zn , Cr and Al . This method was suitable for comparatively weak complexes log K -; 8 . The Ž . second method took advantage of ligand competition between sulfide and 8-hydroxyquinoline oxine for free metal ions. The ability of the oxine to form electroactive complexes with Cu 2q , Cd 2q , Pb 2q , Zn 2q , Co 2q and Ni 2q , was used to detect the concentration of the metal-oxine complexes in equilibrium with sulfide. More stable complexes could be detected by this method. The two independent methods could be compared for some metals showing good agreement. The stability of the sulfide complexes with copper was found to be much greater than previously determined, in line with theoretical q Ž . prediction. The high stability, greater than that for Ag , suggests that copper may be complexed by sulfide as copper I Ž .2q 2q rather than copper II . Complex stability with Co and Cd is also greater than found before, but the difference is smaller. The stability constants were used to calculate the speciation of sulfide at realistic sulfide and metal concentrations similar to those present in the open ocean. At a sulfide concentration of 0.5 nM and a copper concentration of 1 nM in Ž . Ž Ž . q . seawater, the major form of sulfide is copper II monobisulfide Cu HS representing 99% of the total sulfide. In the Ž . presence of natural organic complexing ligands a smaller percentage 28% of sulfide was bound to copper, the remainder occurring as bisulfide, whereas copper was then 71% complexed by organic matter. The new data and the calculations confirm the potential importance of sulfide as a complexing ligand in seawater, more important than major anions and competing effectively with natural organic ligands. q
