Florisil Synthesizing And Additive Altering And Applying It To Pesticide Analysis

Since China has entered the World Trade Organization, we have been faced with developed trade protectionist pressures that are higher level testing technology of pesticide residues, which became guardian angel of conservatism. To withstand that, we must improve our monitoring technology of pesticide residues, Silicon-Magnesium adsorbent, which was used for eliminating impurities of pesticide residue analysis and industrial adsorption, is demanded huge by market, but the products quality of enterprises in China can not be up to scratch to meet the demand. And there are lots of imports from abroad every year. Because of high regard for pesticide residues nearly years and the press from international trade bulwark, we have high regard for pesticide residues analysis more and more. At the same time, the price of florisil is becoming more and more. So we have to break international forestall depending on technic to end the florisil market requirement embarrassment. The design is meant to address this demand into practice.Florisil (magnesium silicate carrier, most component is six magnesium silicate), which is also named as Silicon-Magnesium adsorbent, is the most commonly used adsorbent in the purifying of pesticide residue analysis. The product that is from the reaction of magnesium sulfate and sodium silicate, under filtrating and drying the magnesium silicate, is porous solid precipitate with a huge surface area and is used the most of the world most-adsorbent, and that is a high selective adsorbents, which adsorbed polar molecules from non-polar matrix strongly under obverse-phase condition. This paper focuses on enhancing its adsorption capacity through put five superficial additive into each Florisil, and test its adsorption capacity through its methylene-blue adsorption. Undergo a performance test with applying it to pesticide residue analysis.And the test result is:Florisil with superficial additive is great and its practicality performance is good at precision and veracity, which can substitute input product to satisfy the requirements of pesticide residue analysis. Through synthesizing and altering silicone Florisil, strengthening our monitoring technology of pesticide residues with lower cost, we make our efforts to improve monitoring level, and break the trade barriers between the world.
