Effects of various factors on gold recovery from pregnant solution were discussed. Linear Formula (NH 4) 2 S 2 O 3. Ammonia, hydrogen sulfide, and oxides of nitrogen and oxides of sulfur may form in fires (USCG, 1999). %PDF-1.3 %���� Number of times cited according to CrossRef: Nitrogen Loss Inhibitors Evaluated for Humid‐Region Wheat Production. Ammonium thiosulfate is a preferred source of sulfur in clear solution fertilizers because it allows for much higher nutrient analysis in finished blends than ammonium sulfate. Use splash-proof chemical goggles or face shield to prevent splashes from contacting the eyes. Ammonium thiosulfate acts as a sulfur supplier. Selective recovery of Au from pregnant solution was obtained using Cu. Manufacturer: PCI Nitrogen, LLC 713-920-5300 2001 Jackson Rd © 2019 Elsevier B.V. All rights reserved. Levels of inhibition ranged from 15–35% with a 1% (v/v) addition of ATS to UAN to 40–52% with 10% (v/v) inclusion. To obtain the pure compound, gently heat the solution for several hours at ~90 °C, then cool the concentrated solution to crystallize the compound. It is white crystalline solid with ammonia odor, readily soluble in water, slightly soluble in acetone and insoluble in ethanol and diethyl ether. Three commercial sources of ATS were compared to reagent sodium thiosulfate, at equal rates of sulfur, and all sources inhibited soil urease similarly. US State regulations No additional information available SECTION 16: Other information NFPA health hazard : 1 - Exposure could cause irritation but only minor residual injury even if no treatment is given.

A variety of fertilizers are produced by various mixing methods based on ATS. *ORAL LD-50, mg/kg, male rat SECTION III PHYSICAL/CHEMICAL CHARACTERISTICS … (USCG, 1999). Incubation studies at 25°C with a Williams loam (Typic Argiboroll) illustrated that the thiosulfate ion is an inhibitor of nitrification. Percent inhibition was greater after 28 than 14 d of incubation. MDL number MFCD00015965. In contrast, the recovery of Au ions via cementation was more favorable in the absence of oxygen. PubChem Substance ID 24860416. Leaching mechanisms of metals in ammonium thiosulfate system were investigated. It contains 30-60% ammonium thiosulfate by mass. Agricultural Management of Enhanced‐Efficiency Fertilizers in the North‐Central United States. : NH4OH Fig. Although the nitrification and urease inhibition properties of ATS are less than have been reported for some other materials, ATS deserves further laboratory and field evaluation as a possible nitrification and urease inhibitor.
