室外空气中的甲醛有两个来源,分为自然和非自然。自然来源包括挥发性有机物通过光反应形成的甲醛,腐殖质被阳光照射产生的甲醛和一些细菌、藻类、浮游生物与植物体内存在的低浓度的可以排放到空气中的甲醛 [4] 。甲醛的非自然来源包括各种燃料的燃烧、森林火灾和工厂废气以及汽车尾气的排放,据有关报道显示城市空气中甲醛的年平均浓度大约是0.005~0.01 mg/m3,一般不超过0.03 mg/m3,这部分气体在一些时候可进入室内,是构成室内甲醛污染的一个来源 [4] 。

在许多室内产品中,如压木、涂布纸制品、油漆、保温材料等,都可以发现甲醛污染物。而长时间的曝光在0.10 × 10−3 mg/m3或更高浓度的甲醛环境中就可以对人体健康造成一定的伤害,如恶心、胸闷、皮疹和过敏反应 [5] 。由于甲醛的大量排放源,室内甲醛的浓度可以从1.00 × 10−3 mg/m3到超过0.10 mg/m3,而美国毒物与疾病登记署表明大多数人在室内花的时间占80%到85%,这对人来说无疑是一种慢性自杀 [2] 。

一方面,在工业的观测结果中,甲醛一直被认为对人类皮肤表面有急性刺激 [6] 。根据暴露的个体对甲醛是高度敏感还是处于平均敏感度,我们把它分为以下几个级别:对眼产生刺激性的甲醛浓度在0.05 × 10−3 mg/m3和1.00 × 10−3 mg/m3之间,对鼻腔和咽喉产生影响的浓度在0.11 × 10−3 mg/m3左右,使人咳嗽的浓度在5 × 10−3 mg/m3至0.030 mg/m3之间 [6] 。

4.1.1. 英文标题MnO2改性活性炭除甲醛

MnO2是一种强氧化剂,可以与活性炭结合起来去除甲醛。利用浸渍法改性活性炭(将高锰酸钾和活性炭混合并进行烘培,改性是为了使活性炭具有特定的吸附和催化性能),制得负载有MnO2的活性炭,而此种新型复合物对甲醛的去除是物理吸附和化学催化共同作用的结果 [7] 。马国斌等 [8] 研究了此种方法对甲醛的去除并且比较了不同条件(甲醛的初始浓度、负载有MnO2的改性活性炭的投加量、温度、pH等)对甲醛去除效率的影响。其复合物最佳制备条件:KMnO4浸渍液浓度为0.079 mol/L,焙烧温度为 600 ℃ 。最佳吸附条件: 35 ℃ ,pH = 7。过酸会破坏MnO2稳定性,过碱会阻碍甲醛的吸附。值得注意的是,负载有MnO2的改性活性炭在吸附甲醛时候也会饱和,使得去除甲醛的效果减弱,所以当饱和之后还要进行脱附再生。

4.1.3. Sc-TiO2-Ac去除甲醛

二氧化钛是一种白色固体,由于其优异的光催化氧化能力(光腐蚀性、无毒性),已成为占主导地位的催化剂 [10] 。Sc-TiO2-Ac是由TiO2和活性炭在超临界(超临界状态:物质的压力和温度同时超过它的临界压力和临界温度的状态)乙醇条件下制成的一种TiO2-活性炭复合材料 [11] 。为了验证此种复合物的甲醛去除能力,黄彪等 [11] 首先在控制其他条件相同的前提下,比较活性炭、Sc-TiO2、活性炭和Sc-TiO2简单混合物去除甲醛的效果。结果表明三种物质对甲醛的去除效果呈递增趋势,虽然活性炭和Sc-TiO2简单混合物在最初吸附甲醛比较慢,但是经过适宜时间后去除效率也可达到95%。但甲醛在UV照射下会可能发生部分解吸的情况。进一步地,他们在超临界乙醇条件下制备出Sc-TiO2-Ac复合物,解决了甲醛的解吸问题,并使甲醛去除率可达到100% [11] 。这归功于此复合物具有光催化和吸附的协同效应。其中光催化的作用有两个:一是加快降解速率,二是促使被活性炭吸附的污染物向TiO23D跨度走势图带连线表面迁移,使活性炭的吸附能力得以恢复,实现原位再生。

光催化是一种新兴的、有着较好前景的技术,它的优点主要是可以在室温下操作,并能在光下降解许多有机物 [10] 。在室温和大气压力下使用二氧化钛作为催化剂,并在紫外光的照射下,可以将挥发性有机物氧化成二氧化碳和水,最终使室内空气得到净化 [5] 。然而,大部分降解污染物的研究表明,紫外线或者二氧化钛单独作用时效果并不理想,所以通常采取一些措施来提高甲醛的去除效率,例如把紫外线和二氧化钛结合起来、将TiO2固定在吸附材料上或者加入一些其他物质 [12] 。

3D跨度走势图带连线4.2.1. YIGUIJIAOWEIZAITI

硅胶是一种化学性质极其稳定的物质,和活性炭相似,也具有多孔结构,故可作为吸附剂。刘红敏等 [12] 把硅胶作为TiO2载体,利用溶胶-凝胶法将改性后的高效TiO2光催化剂负载于球形硅胶上,保持其他条件相同,在设计的两个管道内做对比试验,检测最后的甲醛浓度,发现相同时间内以硅胶为载体的光催化甲醛去除率比没有硅胶作为载体的高了30%。

臭氧O3,是一种有特殊气味的淡蓝色气体,具有强氧化性,可杀菌。化学性质极不稳定,在室温下可缓慢分解成氧气。有人将臭氧与光催化技术结合起来探究去除甲醛的效率。卢静霞等 [13] 研究了UV/O3、TiO2/UV、TiO2/UV/O三种催化条件下甲醛的去除效率。结果表明:在相同条件,三种催化方法均有降解甲醛的作用,但TiO2/UV/O33D跨度走势图带连线去除效果最好。这是因为除了简单的吸附与降解,光催化还和臭氧发生了协同作用。

4.2.3. PANi/TiO2-SiO2除甲醛

聚苯胺(PANi)具有良好的氧化还原性和光转换性质(即受光照辐射时能产生电流),并且具导电率高,稳定性好的特点,所以利用它同二氧化钛、二氧化硅可制成一种PANi/TiO2-SiO2复合催化剂。赵世博等 [14] 利用PANi的导电性和光敏化性,来改变TiO2在紫外和可见光下的光催化性能,并探究不同因素对复合物去除甲醛的影响。结果表明:负载有PNAi的催化剂比不带有PANi的催化剂效果更好。原因有两个,一是PANi对甲醛有较强的吸附作用,二是其直接或间接的促进了氧化反应。其他因素,比如PANi不同负载量、有机酸和盐酸掺杂、不同负载层数等都可以在不同程度上影响甲醛去除率。
