ZnS was synthesized as a new photocatalyst material by electrodeposition. We attempted to synthesize ZnS using electrolytic baths containing metal ions and various complexing agents, i.e., tartaric acid, citric acid, triethanolamine (TEA), and disodium ethylenediaminetetraacetic acid (EDTA-2Na). The crystalline properties, binding conditions, surface morphology, and chemical composition of the samples were examined by X-ray diffraction (XRD),X-ray photoelectron spectroscopy (XPS), respectively. ZnS was synthesized from all electrolytic baths examined except that using malonic acid as a complexing agent. However, X-ray photoelectron spectroscopy (XPS) suggested that metallic Zn was also present in the ZnS deposits. The band gap energy of ZnS prepared using EDTA as a complexing agent ranged from 3.4 to 3.5 eV, lower than the value of 3.6 eV for pure ZnS, indicating that metallic Zn present in the ZnS deposit reduced the band gap energy.

“…The accumulation of data and the knowledge of process optimization accompanying the distribution of such technologies will contribute to an expanded market for secondary urban phosphorus resources, and this will translate into a stable supply, both qualitatively and quantitatively. Among the many technologies already developed, the sulfide precipitation technique (Okamoto, Miyamoto et al 2012) and the dry-melting furnace methods, which involve significant infrastructure costs, are capable of providing a stable supply and the quantity and quality that an expanded market will require, and will be cost-effective in the long-term.…”

Due to the impact of increasing global demand for high-grade steel for a variety of applications at a time when high grade iron ore reserves are becoming depleted, the removal of impurities, and especially phosphorus, has become essential. Demand in the rapidly growing car industry, in particular, is increasing pressure on steelmakers to provide high quality steel. The dephosphorization step presents new opportunities to steelmakers: besides producing high-quality steels not prone to cracking or corrosion, and improving production efficiency, steelmakers are presented with the opportunity to recover phosphorus and market it as a value-added product. Another industry with potential to recover P as a secondary product is the surface treatment industry. Surface treatment and the galvanization of metal products requires phosphoric acid and generates waste containing phosphorus, which is typically not well recovered or recycled. In this study, we focus on the potential of steelmaking slag and waste sludge from nickel plating and metal surface treatment processes as non-traditional phosphorus resources. An MFA on the hidden phosphorus flow behind global iron ore trade showed that, that the hidden flow of phosphorus from the three major iron ore export countries to China alone was 331 kt in 2013, which is equivalent to 1.7% of the global consumption of P in fertilizers consumed that year. In 2013, 3.6 kilo ton of phosphorus was wasted in acid waste from the metal surface treatment industry.
