“…Recently, great effort has been focused on finding approaches to synthesis sulfur nanoparticles (SNPs) with well-defined shapes and nano-sizes. Among these, reverse microemulsion (Guo et al, 2006;Desphande et al, 2008), an electrochemical (Shamsipur et al, 2011), water-in-oil microemulsion (Soleimani et al, 2013), an aqueous solution of potassium polysulfide and various organic and inorganic acids (Massalimov et al, 2012), ultrasonic technique (Xie et al, 2009), green solvents (Xie et al, 2012), surfactant assisted route (Chauhuri & Paria, 2010), supersaturated solvent (Wu et al, 2008), chemical precipitation (Meenatchi & Renuga, 2015), and membrane as natural biomaterial (Cheng et al, 2011). These methods have many disadvantages due to the difficulty of scale up the process, separation and purification of nanoparticles from the micro emulsions and energy requirements.…”

The objective of this research work is to synthesize sulfur nanoparticles by green route and to investigate the beneficial effect on root and shoot growth of tomato. Sulfur nanoparticles (SNPs) synthesized using aqueous extract of Ailanthus altissima leaves at room temperature. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) inspections indicated that nanoparticles are spherical and polydispersed with diameters ranging between 5 and 80 nm. The potential of sulfur nanoparticles for enhancing tomato's growth, increasing the concentration of sulfur nanoparticles from 100 ppm to 300 ppm cause an increase in root and shoot lengths, while higher concentration 400 ppm and 600 ppm induced an inhibitory effect. Results of this study reveal that SNPs have the potential to enhance root and shoot growth of tomato and the effect is concentration dependent.

“…Recently, great effort has been focused on finding approaches for synthesis sulfur nanoparticles (SNPs) with well-defined shapes and nano-sizes. Among these, sulfur nanoparticles synthesized from H 2 S gas by using biodegradable iron chelates catalyst in reverse microemulsion technique (Deshpande et al, 2008;Guo et al, 2006), an electrochemical method using thiosulfate ion (Shamsipur et al, 2011), water-in-oil microemulsion system using cyclohexane as oil phase, butanol as co-surfactant, nonionic surfactant Triton X-100 and sodium polysulfide (Soleimani et al, 2013), an aqueous solution of potassium polysulfide and various organic and inorganic acids (Massalimov et al, 2012), sublimed sulfur in ethanol using ultrasonic technique (Xie et al, 2009), dissolving sublimed sulfur in a green solvent PEG-400 (Xie et al, 2012), aqueous surfactant (Chaudhuri andParia, 2012), supersaturated solvent method (Wu et al, 2008), heating sulfur powder with polyethylene glycol PEG-600 (Meenatchi et al, 2015), and eggshell membrane as natural biomaterial (cheng et al, 2011). These methods have many disadvantages due to the difficulty of scale up of the process, separation and purification of nanoparticles from the microemulsion (oil, surfactant, co-surfactant and aqueous phase), and consuming huge amount of surfactant.…”

The major objective of this research paper is to synthesis sulfur nanoparticles (SNPs) by green route, which can improve plant’s growth and reduce the environmental pathogens. Sulfur nanoparticles (SNPs) were synthesized by a simple green procedure using Melia azedarach leaves aqueous extract and citric acid. The leaves of Melia azedarach aqueous extract act as a capping and stabilizing agent in the formation of sulfur nanoparticles. The synthesized sulfur nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The average particles diameter size was found to be 20 ± 4 nm. Analysis showed that the nanoparticles are crystalline in nature, with spherical shape. A preliminary field study was conducted to evaluate growth and development of Cucurbita pepo in response to sulfur nanoparticles.

“…The effects of different experimental conditions such as reactant concentration, temperature, sonication, types of used surfactants, and their concentration are found to influence growth kinetics of S NPs [ 19 - 22 ]. The coarsening rate constant was found to be highly dependent on the type of acid used as a catalyst [ 21 , 22 ].…”

Chronoamperometric study of elemental sulphur (S) nanoparticles (NPs) in NaCl water solution: new methodology for S NPs sizing and detection

et al. 2015

BackgroundElemental sulfur (S) persists in natural aquatic environment in a variety of forms with different size distributions from dissolved to particulate. Determination of S speciation mainly consists of the application of chromatographic and electrochemical techniques while its size determination is limited only to the application of microscopic and light scattering techniques. S biological and geochemical importance together with recent increases of S industrial applications requires the development of different analytical tools for S sizing and quantification. In recent years the use of electrochemical measurements as a direct, fast, and inexpensive technique for the different nanoparticles (NPs) characterization (Ag, Au, Pt) is increasing. In this work, electrochemical i.e. chronoamperometric measurements at the Hg electrode are performed for determination of the size distribution of the S NPs.ResultsS NPs were synthesized in aqueous medium by sodium polysulphide acidic hydrolysis. Chronoamperometric measurements reveal the polydisperse nature of the formed suspension of S NPs. The electrochemical results were compared with dynamic light scattering measurements parallel run in the same S NPs suspensions. The two methods show fairly good agreement, both suggesting a log-normal size distribution of the S NPs sizes characterized by similar parameters.ConclusionsThe preliminary results highlight the amperometric measurements as a promising tool for the size determination of the S NPs in the water environment.
