Description
(一)技术领域
本发明涉及一种皮克林乳液微球,特别涉及一种固定光合细菌皮克林乳液微球及制备方法以及在降解有机废水中的应用。
(二)背景技术
皮克林乳液是一类用固体颗粒替代表面活性剂来稳定乳液的总称。与利用表面活性剂稳定的乳液相比,皮克林乳液具有更好的稳定性,避免因使用表面活性剂对生物分子活性带来的不利影响。此外,皮克林乳液的制备受多种因素影响,如颗粒浓度、颗粒润湿性、颗粒粒径、界面颗粒的相互作用、油相性质、油/水比、电解质、颗粒初始分散相介质等。
一般地,非极性油相使颗粒更亲水,易倾向形成O/W型乳液;极性油相使颗粒更亲油,易形成W/O型乳液。在一定颗粒浓度下,油/水比的改变会导致乳液在O/W和W/O之间改变,称之为转相。适宜的油/水比对乳液的稳定非常重要。适当的颗粒絮凝可以改善皮克林乳液的稳定性,在电解质作用下,微絮凝颗粒的稳定效果最好。固体颗粒的表面愈粗糙,形状愈不对称,愈有利形成牢固的颗粒“膜”,使乳液更稳定。
一般地,所形成的皮克林乳液的稳定性会随颗粒浓度增加而提高,同时乳液半径也随之减少。在达到一定浓度后,再继续增大颗粒浓度将不会对乳液的稳定性及乳液半径有较大的改变。当固体颗粒的直径小于几个微米时,乳液的稳定性会迅速增加,且颗粒必须小于分散相液滴尺寸,才能有效地稳定乳液。当油/水界面能大于颗粒/油相和颗粒/水相的界面能之差的绝对值时,颗粒可以自发吸附到油/水界面上。
用于皮克林乳液稳定的颗粒一般有两种:一种是均匀润湿性的,另一种是两亲性(Janus)颗粒。一般地,利用两亲性(Janus)颗粒制备的皮克林乳液更稳定。
明胶由18种氨基酸组成,其中脯氨酸(Pro)和羟脯氨酸(Hyp)含量较高。选择明胶作为金属有机骨架材料(MOF)的生长基质,一是其廉价且无毒,二是明胶中丰富氨基酸可诱导MOF生长。沸石咪唑酯骨架材料(ZIF-8)生长的关键在于两相界面反应的生长调控。现阶段制备的MOF微球多采用“液滴微流控”装置,即使用两种互不混溶的液体(分别含金属源和有机配体)通过注射泵在“液滴微流控”的T型接头处发生界面反应,继而生成MOF微球。由于该设备复杂、成本高,很大程度上限制该技术只应用于实验室阶段。
(三)发明内容
