“…6) A comparison between the analytical characteristics of the proposed method and literature methods for H 2 S determination is summarized in Table 1. It can be seen that our method has a higher sensitivity than electrochemistry [12], ICP-AES [14], CL method [16], and fluorescence method [37]. Its sensitivity is slightly lower than that of the reported HGAFS technique, but the proposed method is more simple than the HGAFS method [38].…”

“…Thus, H 2 S is an important molecule involved in many biological processes, and various techniques have been developed for determination of H 2 S concentrations in different samples. Some of the common H 2 S determination methods include electrochemistry [12,13], inductively coupled plasma atomic emission spectroscopy (ICP-AES) [14], gas chromatography [15], chemiluminescence (CL) methods [16], colorimetry [17], and the methylene blue assay [18]. These methods provide excellent performance, but they are generally complicated, costly, and time-consuming.…”

We have developed a green approach to prepare DNA-templated silver nanoparticles (Ag-NPs) from the direct reaction between Ag and ascorbic acid in the presence of DNA and sodium hydroxide. The Ag-NPs showed strong resonance light scattering (RLS) intensity property. Then, the interaction between hydrogen sulfide (HS) and Ag-NPs was studied by measuring their RLS spectra. The results showed that there is a strong interaction between Ag-NPs and HS, which resulted in a decrease in the size of Ag-NPs and a decrease in the RLS intensity of the Ag-NPs solution at the wavelength of 467 nm. The results demonstrated that the RLS technique offers a sensitive and simple tool for investigating the interaction between Ag-NPs and HS, which can be applied to detect HS with high sensitivity and selectivity without complex readout equipment. The linear range for HS determination was found to be the range from 5.0 × 10 to 1.0 × 10 mol L, and the detection limit (3σ/k) was 2.8 × 10 mol L. Moreover, the proposed method was applied for the determination of HS in natural water samples with satisfactory results. Graphical abstract The application of Ag-NPs in HS detection.

This study reports 2 new simple derivatization-based dispersive liquid-liquid microextraction (DLLME) methods for spectrophotometric ultratrace determination of asulam and sulfide. 1-Naphthol (in the presence of nitrite) and N,N-diethyl-p-phenylenediamine (in the presence of Fe(III)) were used to derivatize asulam and sulfide, respectively.In the enrichment methods, the formed derivatives were preconcentrated into microdroplets of the in situ formed water insoluble ionic liquid (IL), 1-hexyl-3-methylimidazolium hexafluorophosphate. Monitoring was performed at 526 nm for asulam and at 664 nm for sulfide, after dissolution of the IL-rich phases into the basic ethanolic solution and ethanol for asulam and sulfide, respectively. Beer's law was obeyed in the ranges of 1.0-80.0 and 0.1-5.0 ng mL −1 for asulam and sulfide, respectively. Limits of detection for asulam and sulfide determination by the DLLME methods were 0.18 and 0.019 ng mL −1 , respectively. Various foreign cations, anions, organics, and pesticides were tested to evaluate the selectivity of the DLLME methods. The methods were successfully applied to the determination of asulam and sulfide in various environmental, wastewater, and urine samples.

“…In environmental waters, decomposition of organic matter and the activity of sulfate-reducing bacteria lead to the formation of hydrogen sulfide (Patnaik 1999;Yao and Millero 1996). This gas is a very important pollution index for water (Colon et al 2008). It exists naturally in crude petroleum, natural gas, hot springs and foods.…”

A simple spectrophotometric method for determination of hydrogen sulfide in wastewater and hot spring samples was developed. The method is based on the reaction between hydrogen sulfide and sodium 1,2-naphthoquinone-4-sulfonate (NQS). The effect of various experimental factors on the reaction between hydrogen sulfide and NQS was investigated and optimized using central composite design. The optimal values of the factors were 5.00 9 10 -4 mol L -1 for concentration of NQS and 1.00 9 10 -2 mol L -1 for concentration of hydrochloric acid. The wavelength of the maximum absorption of the reaction product was 320 nm. Constructed calibration curve for hydrogen sulfide determination was linear in the range of 0.5-20.0 mg L -1 with the detection limit of 0.16 mg L -1 . The method was free from interferences. Percent relative errors below 2 % were obtained for determination of hydrogen sulfide in environmental samples.
