The Study Of Determination Of Strontium In Titanate By Gas Flotation-FAAS

Titanate salt compounds with the advantage of wide source of raw materials, low cost, simple synthesis method, easily modified and doping, are a series of high-value-added and broad prospects for development of fine chemical products. With the development of the electronics industry, particularly the sensitive components of the production requirements and the establishment of quality management system, it needs the higher quality control of electronic components' raw materials increasingly. The direction of trace and even more trace is the Titanate series' indicators of impurities in raw materials. Therefore, the corresponding simple, reliable method of analysis has become the subject of people's attention.The sensitivity of flame atom absorption spectroscopy (FAAS) in the alkaline earth metals becomes lower sensitivity, coupled with a large number of its titanium matrix interference.Series of raw materials and titanium impurities in the metal content is also relatively low in this, the use of the existing ministerial standard test, the lower the value of the response, apparatus, relatively large measurement errors. In this paper, in order to solve the FAAS determination of alkaline earth metal in a lower sensitivity of the issue have been introduced by a sense of its flotation. First of all, try a variety of trapping agents and the flotation effect of organic solvents, found in 18 acid and methyl isobutyl ketone best combination, and then identified by orthogonal experiments determined the best conditions, then under optimal conditions study of organic reagents for the enrichment of alkaline-earth metal strontium effect, results showed that the acid 18 and methyl is obutyl ketone best combination.In this paper, we do a preliminary test of the 18 crown - picric acid system, the impact of extraction of strontium, resulting in a variety of conditions can not be made better extraction results.In this paper, the mechanism of flotation is that the arrested are usually set of material adsorbed on the surface with bubbles of air rising into the organic phase, the bubble in the organic phase after the breakdown of which remain in the. In this paper, the fatty acids used in the flotation of the strontium ion is divided into three-tier system, the first layer is a foam layer, the middle layer of emulsion layer, a layer of water below the water phase of the emulsion layer and the foam layer in the methylisothiourea butyl ketone ketone when just joined has been dissolved into the organic phase, are part of extraction. Residual aqueous phase and 18 in the strontium is adsorbed on the surface of bubbles, with rising air bubbles into the organic phase, with the bubble in the organic phase of the rupture, and ultimately dissolved in organic phase.
