“…In nature, it occurs in deposits of coal, oil and in mineral ores (NRCC, 1977). Another source is the wastewater of various industries which is considered to be heavily adulterated with sulfide ions (Murugananthan et al, 2004;Mckee and Wolf, 1963;USEPA, 1976;Booras, 1974;Colby and Smith,1967). Through anaerobic decay of organic matter, sulfur found in fertilizers, fungicides and sewage, sulfate reducing bacteria generate sulfides (Mckee and Wolf, 1963;USEPA, 1976;Adelmah and smith, 1972;Acree and Splittstoesser, 1972).…”

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.

“…A direct exposure of H 2 S in body, even in minute concentration results in pain, tearing, blurred vision, photophobia, conjunctivitis, corneal bullae ( Sax, 2014;Meyer, 1977). Hydrogen sulfide is also found to deactivate and degrade the key enzymes in human body (Murugananthan et al, 2004).…”

“…It may explain why plant operator and people surrounding treatment plant frequently complain of having headache and feeling nauseous. Diffusion of absorbed H2S in blood plasma to bones, spleen, lungs, liver, kidneys, pancreas and small intestine has also been reported [7]. While sulfide is corrosive and may cause pipe fouling due to deposition [8].…”

“…Processes for electrochemical treatment of effluents have been described in the literature since 1903. In recent years interest has been growing, especially because of its simplicity of operation and application to treat various types of effluents from various sectors, such as domestic sewage [27], laundries [29], restaurants [30] steel mills [31], textile mills [32], and tanneries [33], facilitating the removal of metal ions [28], fluoride ion [34], boron [35] and oils [7,[36][37][38][39][40][41].…”
