• 物質的量

  In order to obtain the best condition, bulk polymerization isfirstly carried on the study of the functional monomer, crosslinker,initiator andreaction conditions on the preparation and performance of MIPs by the single factorand orthogonal experiment, the superior condition is that Theα-Methyl Acrylic Acidis used as a functional monomer, Ethylene Glycol Dimethacrylate is used ascrosslinking agent, the ratio is 1:4:20, chloroform is used as a solvent,2,2'-Azobisisobutyronitrile is used as initiator, the amountis 60mg, reactivetemperature is 60℃, L-tyrosine molecularly imprinted polymers (MIPs) of goodadsorption properties can be produced, the extraction efficiencies is as high as 86.57%,saturation adsorption is as high as 77.66μmol/g. Then molecularly imprinted polymer in the aqueous suspension system iscomparatively studied, its optimal reaction conditions: Mixing speed is 200r/min, theratio of amount of substance among L-Tyr, MAA, EDMA is 1:4:20, the amount ofAIBN is 6.0g, 60℃water bathing,by this, L-tyrosine imprinted polymermicrospheres (MIMs)polymerization in relatively small average size (61μm) canbe produced.
  為了得到最優(yōu)合成條件，首先采取本體聚合法制備L-酪氨酸分子印跡聚合物(MIPs)，通過單因素實驗和正交實驗，研究了功能單體、交聯(lián)劑、引發(fā)劑及反應條件對制備MIPs及其性能的影響，得出最優(yōu)條件為：α-甲基丙烯酸(MAA)為功能單體，二甲基丙烯酸乙二醇酯(EDMA)為交聯(lián)劑，其物質的量之比為1：4：20，以氯仿作為溶劑，偶氮二異丁腈(AIBN)作為引發(fā)劑，用量為60mg時采用60℃加熱聚合的方法，制備吸附性能良好的L-酪氨酸的印跡分子聚合物MIPs，其萃取效率高達86.57％，飽和吸附量高達77.66μmol／g。
