Synthesis and characterization of sulfur nanoparticles with WSP/surfactants mixtures

Abstract

Sulfur nanoparticles display unique physical and chemical feature because of effects such as the quantum size effect, mini size effect, surface effect, and macro-quantum tunnel effect. Therefore, sulfur nanoparticles would present higher efficacies such as removal of heavy metals, radical-scavenging, antimicrobial activity, antioxidant and antitumor activities. They have been using as a fungicide product in agriculture and medicine; to obtain sulfur fertilizers and cosmetics industries, as well as in obtaining nanocomposite lithium batteries; to form stable carbon chains such as C 3 S and C 5 S for obtaining hybrid materials with useful properties for gas sensor and catalytic applications. This work presents the results of obtaining sulfur nanoparticles, which can be used in agriculture as a fungicide treatment. Sulfur nanoparticles were obtained by modifying the surface of sulfur by various water-soluble polyelectrolyte (WSP)/surfactant mixtures including NaCMC/CTAB, PDADMAC/SDBS, NaCMC/Triton X-100 (TX-100). The size and the structure of sulfur nanoparticles were determined by methods as LSA, XRD, SEM. It is shown that the nanoparticles have a sulfur monoclinic α-form, and their average size is in the range of 100-300 nm. The received products can be considered as perspective forms of application in agriculture and medicine.

Nanoscale Sulfur Improves Plant Growth and Reduces Arsenic Toxicity and Accumulation in Rice (Oryza sativa L.)

“…41−43 Nanoscale sulfur (NS) has many unique physical and chemical features, including quantum size, high surface area, and macroquantum tunnel effects, which provide advantages over conventional sulfur. 44 Further, NS can have various advantages over BS and other methods used for alleviation of As accumulation and toxicity. Lower application rate, slow release, and the added fertilization effect of nanosulfur make it a promising alternative to other methods to deal with As toxicity and accumulation in rice.…”

Easy Handling Preparation of Cubic Sulfur in Aqueous Extract of Sapindus rarak rinds

“…For example, Triton X-100 and butanol are effective as surfactants and co-surfactants in forming monoclinic sulfur particles from a sodium polysulfide solution (Soleimani et al, 2013), respectively. The further research of the effects of the surfactants was conducted by modifying sulfur surfaces using watersoluble polyelectrolyte/surfactants (Turganbay et al, 2019). Interestingly, saponin, a natural surfactant extracted from Acanthe phylum bracteatum, was also employed in synthesizing monodispersed SNPs (Kouzegaran and Farhadi, 2017).…”

“…!» -дейді.Мақаланың негізгі түйіні: «...әуелі өзін, онан жақынын, онан Отанын, онан кейін барып бар адам баласын сүю табылу керек. Жақынын, ұлтын сүймеген адам салғаннан барлық адамды жақсы көреді дегенге сенбеймін»[3].Адам баласының бойындағы өзімшілдік қасиетті асқан шеберлік, дәлелді мысалдармен сипаттайды: «Әке мен бала суға бата бастаса, ортасында жалғыз тақтай болса, екеуі су бетінде сол тақтайға таласады.Теңіз жүзінде адасып, азықтары таусылып аштан өліп бара жатқан адамдар бірінбірі пісіріп жейді, кісіде өзін жақсы көретін өзімшілдік қандай күшті екенін осы мысалдар көрсетеді». Бұл жерде сынға алғаны -көп адамдардың жұрт ісіне жұмылуға мойыны жар бермей, өз қара басының ғана қамын күйттейтіні.…”
