“…The electrode exhibited a linear response range to sulfate species in the range of 10 −6 to 10 −3 M with a detection limit of 2 × 10 −6 M and a good sensitivity based on the Nernstian slope within the pH range 4-10. Lomako et al (2006) also evaluated a sulfate-ISE based on the composition of a neutral carrier and a quaternary ammonium salt. The ISE was used for the determination of sulfate in seawater, mineral water and urine by a direct potentiometric method and potentiometric titration, resulting in relative errors below 7%.…”

A variety of anthropogenic activities, especially at industrial level, generate wastewater streams rich in sulfate which, if improperly treated, can cause health, social and environmental problems (Serrano et al., 2020). These industrial activities include food production (e.g. edible oil, seafood-processing), fermentation industry, tanneries, coal-burning power plants, paper and pulp industry, mining and metallurgical processes. Additionally, in some regions (e.g. Hong Kong), the use of seawater for toilet flushing to alleviate the pressure on potable water has increased the sulfate concentration in municipal sewage (Li et al., 2018; Wu et al., 2016). Anaerobic digestion (AD) is a well-established technology to transform municipal and industrial organic-rich wastewaters into renewable energy in the form of methane-rich biogas. Besides energy recovery, AD presents other important advantages compared to aerobic treatment such as low sludge production and low energy requirements (Puyol et al., 2017). AD is also a suitable technology to treat organic-rich municipal and industrial wastewaters containing sulfate. However, a high sulfate content can affect the AD process performance and feasibility due to (i) the competition for easily biodegradable organic matter (e.g. short chain fatty acids, hydrogen) between sulfate reducers and anaerobic microorganisms (Cassidy et al., 2015; Kalyuzhnyi et al., 1998), (ii) the generation of H 2 S, the product of sulfate

“…Portions of KNCS were added to the prepared ZnCl 2 solutions to create concentrations 1×10 −1 , 1×10 −2 , 1×10 −3 , 1×10 −4 and 1×10 −5 M SCN − . The starting solutions of ClO 4 − with a concentration of 1.0 M in the presence of various concentrations of ZnCl 2 and KNCS were consecutively diluted with supporting electrolyte solutions to produce a series of ClO 4 − solutions with a concentration from 1.0 to 1×10 −7 M. The starting solutions of NO 3 − with a concentration of 1.0 M in the presence of various concentrations of ZnCl 2 and KNCS were consecutively diluted with supporting electrolyte solutions to produce a series of NO 3 − solutions with a concentration from 1.0 to 1×10−6 separate solution method, in the order of foreign ion lipophilicity increase19 .…”

The influence of the background concentration of ZnCl 2 on the selectivity of Zn(NCS) 4 2-−SE based on QAS to SCN − is studied. The introduction of ZnCl 2 into a solution fixes zinc released from the membrane in the form of thiocyanate complex. A high selectivity of the Zn(NCS) 4 2-−SE to SCN − ions is due to the formation of better extractable complexes between zinc and SCN − compared to acidocomplexes of competitive anions. An introduction of 5.0 M ZnCl 2 into a solution increases selectivity to SCN − ions by 5 orders of magnitude in the presence of interfering ClO 4 − ions and more than 4.5 orders of magnitude in the presence of interfering NO 3 − ions.
