Abstract
本发明公开了一种光催化和物理吸附抗菌再生竹纤维素膜及其制备方法，步骤如下：(1)、再生竹纤维素、纳米二氧化钛、纳米氧化石墨烯加入到2‑甲基‑3‑乙基咪唑氯盐离子液体中，得到再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯多元体系铸膜液；(2)、采用刮膜法将铸膜液均匀刮涂在玻璃板上，采用沉淀相转化法制备0.1～0.5mm的竹纤维素/纳米二氧化钛/纳米氧化石墨烯的抗菌再生纤维素平面膜。本发明制备的抗菌再生纤维素不仅具有光催化反应，同时具有吸附过滤效果，大大提高污水处理能力。
Description
技术领域
本发明涉及一种再生竹纤维素平面膜的制备方法，特别是涉及一种再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯光催化和物理吸附抗菌再生竹纤维素膜的制备方法。
背景技术
当前国内外主要由界面聚合法制备超滤滤膜。在膜材料上，主要包括有机纳滤膜材料(纤维素类、聚酰胺类和聚砜类等)和无机纳滤膜材料(陶瓷材料、金属材料和分子筛等)。在制备方法上，主要有L-S相转化法、界面聚合法、涂覆法、电泳沉积法、共混法、荷电化法、复合法等。
我国做为纺织大国，纺织染整废水总是大量排放，由于其成分相当复杂，颜色深且具有高毒性，如果未得到适当的处理而直接排放到江河等天然水中势必会对人类生存环境造成严重污染和危害。
当前用于染料废水的处理方法主要有物理、化学和生物方法。这些方法可以通过物理吸附、化学催化降解、膜分离、电解、生物处理，氧化和其他过程来处理工业染料废水。在这些过程中，物理吸附过程和化学催化降解方法比其他方法更具竞争优势，因为它们易于获得，成本较低且应用范围更广。但是物理吸附、化学催化降解、膜分离三种处理方式得不到有机结合。
发明内容
为了弥补现有技术存在的不足，本发明的目的是提供一种再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯的光催化和物理吸附抗菌再生竹纤维素膜及其制备方法。
本发明提供的一种再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯的光催化和物理吸附抗菌再生竹纤维素膜及其制备方法，包括以离子液体为溶剂，再生竹纤维素为基材，复合纳米二氧化钛和纳米氧化石墨烯制备得到一种光催化和物理吸附抗菌再生竹纤维素膜；这种再生竹纤维素膜可以将物理吸附、化学催化降解、膜分离三种处理方式有机结合在一起。
发明提供的一种再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯的光催化和物理吸附抗菌再生竹纤维素膜及其制备方法，包括以下步骤：
(1)铸膜液制备：将再生竹纤维素、纳米二氧化钛、纳米氧化石墨烯同时加入到2-甲基-3-乙基咪唑氯盐离子液体中，充分搅拌溶解，形成再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯多元体系铸膜液。
(2)再生竹纤维素制备：将步骤(1)的铸膜液采用刮膜法将铸膜液均匀刮涂在玻璃板上，采用沉淀相转化法制备再生竹纤维素/纳米二氧化钛/纳米氧化石墨烯的光催化和物理吸附抗菌再生竹纤维素初生膜，抗菌再生纤维素初生平面膜经进一步水洗、甘油浸渍、干燥得到光催化和物理吸附抗菌再生竹纤维素膜。
进一步地，步骤(1)中再生竹纤维素：离子液体＝1：(11.5～24)。
进一步地，步骤(1)中纳米二氧化钛质量分数为再生竹纤维素的20％～30％。
进一步地，步骤(1)中纳米氧化石墨烯质量分数为再生竹纤维素的2％～5％。
进一步地，步骤(2)中制备的光催化和物理吸附抗菌再生竹纤维素膜厚度为0.1～0.5mm。
进一步地，步骤(2)中制备的光催化和物理吸附抗菌再生竹纤维素膜干燥方式为真空干燥。
有益效果
本发明的优点和有益效果在于：
(1)本发明提供的制备方法，所使用的原料竹纤维素是自然界中资源丰富的天然高分子材料，价格廉价，来源广泛；而且这个制备过程中不涉及化学反应，同时提高竹再生纤维素的利用率。
(2)本发明提供的一种光催化和物理吸附抗菌再生竹纤维素膜，可以将物理吸附、化学催化降解、膜分离三种处理方式有机结合在一起，从而降低水处理的成本。
