Extraction of antimony and arsenic from fresh and freeze-dried
Abstract. Six extraction media (acetic acid, EDTA, tetrabutylammonium hydroxide, NaOH, MeOH/H2O, acetonitrile/H2O) were tested for their ability to extract antimony Extraction efficiencies were generally low and lower for Sb than for As. Solutions of 0.66 mol L–1NaOH liberated highest amounts of Sb with ~10% for poplar leaves, and ~19% Extraction of antimony and arsenic from fresh and freeze-dried

Selective Extraction of Antimony and Arsenic from Springer
For instance, a decreasing trend is noted in the extraction of both antimony and arsenic when the amount of decopperization slime increased from 50 g/L to 200 g/L (Fig. 6c). On the other hand, Fig. 6 d shows an increasing trend in the extraction of the metals when the leaching time was prolonged.Search worldwide, life-sciences literature Search.

Speciation of Inorganic Antimony in Food and Water Samples
Nano γ-alumina, with ultra-high specific surface area (387.2 m2 g−1), has been synthesized and used as a promising adsorbent material in solid-phase extraction. A simple, sensitive, and economic method was developed for speciation of inorganic antimony by slotted tube atom trapping flame atomic absorption spectrometry (STAT Finally, stability of antimony in plasma was assessed following four freeze–thaw cycles at -20 and -80°C ±10°C utilizing plasma samples spiked with 50 or 7500 ng/ml of antimony standard. Six replicates were analyzed for each concentration and condition and the accuracy and precision for quantitation of antimony under these Inductively coupled plasma mass spectrometry method for plasma

Toxics Free Full-Text Leaching Mechanism and Health Risk
The weathering and leaching of mining tailings have released large amounts of antimony (Sb) and arsenic (As), causing serious pollution in the surrounding soil, water, and sediments. To understand the leaching characteristics of Sb and As in mining tailings, Zuoxiguo and Qinglong mining tailings were collected for analysis. The Sustainable extraction of antimony over a period of 1000 years would only be possible if the global extraction rate would be reduced immediately to 4% of the 2010 extraction rate. The above approach could be considered optimistic, because the existence of coupling mechanisms, e.g. energy scarcity makes metal scarcity worse and Metal scarcity and sustainability, analyzing the necessity to

Natural attenuation processes applying to antimony: A study
Antimony in solid phasesThe wet samples were first dried at room temperature in a fume hood or freeze-dried. The aqua regia total concentrations of Sb and Fe were determined using the same analytical techniques described above for the extracts after a microwave digestion (Milestone) of a subsample in a HNO 3 –HCl (1:3) mixture.Antimony and bismuth typically enter the electrolyte system via the anode. As shown in Figure 1, the concentrations of antimony and bismuth in anodes have been increasing steadily for several decades. Though many impurities precipitate at the anode and become trapped in the anode slimes, some impurities dissolve into the electrolyte,Removal of antimony and bismuth from copper electrorefining

A combination of solvent extraction and freeze thaw for oil
Three groups of experiments were conducted, including freeze/thaw alone, solvent extraction alone, and combined solvent extraction with freeze/thaw. In terms of freeze/thaw treatment alone, a given volume of ultrapure water (Milli-Q ® Advantage A10) instead of solvent was added into the oily sludge, and the mixture of water and oily Antimony (Sb) is highly hazardous to human health even in minute concentration. Therefore, its accurate and precise determination in the real environmental samples is of immense importance. In this work for the first time, UV–Vis spectrophotometric method was developed for the quantification of Sb(III) from water samples using Supramolecular solvent–based liquid phase extraction of antimony

The extraction of Antimony from its ore LEVITY
The extraction of Antimony from its ore Butane is not convenient because it tends to freeze-up the gas bottle, regulator, gas pipe and stop-cocks when used with powerful burners. Charcoal could be also used but such a fuel is more difficult to regulate, regardless of the dust and smoke.A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented.
