摘要
(CN103788308B) 本​发明​涉及​一种​Pickering​乳液聚合​制备​大​孔​印迹​吸附剂​的​方法,属​环境​功能​材料​制备​技术​领域。首先,通过​改良​的​St?ber​法来合​成​二氧化硅​粒子,并使​用​油酸​对其​进行​改性​增强​其​疏水​性;紧接着​通过​改性​的​二氧化硅​粒子​以及​一定量​的​表面活性剂​Hypermer?2296​来​稳定​加入​模板​分子​的​油​包​水​型​的​Pickering​高​内​相​乳液,然后​在​一定​温度​下​聚合,进行​一系列​处理​后​得到​吸附剂,并将​其​应用于​高效​氯​氟​氰​菊​酯​的​选择​吸附​与​分离。制备​的​吸附剂​具有​开孔​的​结构、联结​孔、良好​的​热​稳定性​和​机械​强度​以及​适当​的​疏水​性​等​优点,并且​能够​通过​改变​形成​乳液​的​参数​来​控制​孔​的​形态,提高​对于​模板​分子​的​吸附​容量。该​吸附剂​对于​高效​氯​氟​氰​菊​酯​表现​出​良好​的​吸附​能力​和​选择性​吸附。

(CN103788308B) 1. Pickering emulsion polymerization prepared blot adsorbent one method of macrovoids, characterized in, to the next prepared in accordance with: Preparation of silica particles(1): In a round bottom flask was added ethanol, adding ammonium hydroxide solution and deionized water under magnetic stirring, stirring after 0.5-1.5 h, the addition of tetraethylorthosilicate, mixture at 600-800 rpm speed for 10-14h; the mixture was separated by centrifuge, for which at least three times ethanol rinsed and dried, and then vacuum dried, to obtain silica particles; Oleic acid(2) preparation of modified silica particle: The silica particles was immersed in chloroform and a mixture of oleic acid, stirred for 2-4h, followed by methanol and precipitated collecting oleic acid-modified silica particles, and using chloroform and methanol to remove excess soaking and precipitation and a duplicated respectively of oleic acid, finally in 100-140 Ć under drying, resulting oleic acid-modified silica particles; By(3) Pickering obtained by polymerizing high internal phase emulsion preparation of the selected adsorbents having a porous and specificity: 1st step, W/O type high internal phase emulsion preparation of Pickering: Mechanical stirring, a styrene, polyethylene glycol di (methacrylate) ester, divinylbenzene, acrylamide, -cyhalothrin and a 2, 2 '-azobisisobutyronitrile was added followed by a round bottom flask, a mixture of nitrogen gas and fluid through into the bottle after 30min in the dark for acrylamide and efficient cyhalothrin ju Self Adhesive assembly 10-14h; to 900-1100 rpm agitation and mixture was added to oleic acid-modified silica particles to obtain an oil phase, agitation after 15min, to 300-500 rpm stirring was continued for, at added dropwise within 5min dichloro calcium aqueous to the oil phase, followed by, Hypermer 2296 surfactant was added thereto at the inner 2min Pickering emulsion is stabilized, Pickering W/O type high internal phase emulsion which is to be placed in an ice bath to room temperature to prevent continued due to the increased temperature caused by continuous stirring; 2nd step, preparation of MIPFs: The resulting W/O Pickering type high internal phase emulsion was transferred to centrifuge tubes, at 60-80 Ć and the polymerization was 22-26h MIPFs obtained product, after 100-140 Ć dried in vacuo at 22-26h; immediately the product was purified by washing with a Soxhlet extractor, finally, at 100-140 Ć under drying the purified MIPFs 22-26h.
