【摘要】：雙酚A屬于環(huán)境內(nèi)分泌干擾物,普遍存在與環(huán)境中,可通過干擾生物或人體內(nèi)天然激素的合成、分泌、運(yùn)輸、結(jié)合、反應(yīng)和代謝等過程,從而對生物或人體的生殖、神經(jīng)和免疫系統(tǒng)等的功能產(chǎn)生影響。TiO_2作為具有廣泛應(yīng)用前景的光催化劑,近些年來,一直是國內(nèi)外研究的重點(diǎn)。CuO具有良好的化學(xué)穩(wěn)定性、耐酸、耐堿、低毒、廉價,易于工業(yè)化大規(guī)模生產(chǎn);但是CuO的導(dǎo)帶電位的位置比H2O的還原電位更正,不能滿足光解水產(chǎn)氫對光催化劑導(dǎo)帶電位的要求。本文選用兩種不同粒徑TiO_2(Nano-TiO_2,TiO_2)、納米CuO、碳納米管負(fù)載CuO作為催化劑,研究雙酚A光催化降解動力學(xué),同時考察了TiO_2的量、反應(yīng)液p H值、離子強(qiáng)度、雙酚A溶液濃度各因素作用條件下的光催化性能。具體結(jié)果如下:兩種TiO_2作用下,雙酚A的光催化降解率均在48 h以后達(dá)到平衡,且存在顯著的粒徑效應(yīng)。催化劑的投加量和雙酚A濃度均影響雙酚A的降解率。隨著pH值的升高,雙酚A的光催化降解率均逐漸降低。溶液介質(zhì)中的離子強(qiáng)度抑制了雙酚A光催化降解性,離子強(qiáng)度越高抑制效果越顯著;且兩種粒徑TiO_2的響應(yīng)基本一致。紫外線照射下,Nano-CuO和CuO/MWCNTs催化降解雙酚A的平衡時間為24h;且CuO/MWCNTs的光催化降解性能顯著高于Nano-CuO;Nano-CuO和CuO/MWCNTs的投加量和雙酚A濃度均影響雙酚A的降解率。隨著電解質(zhì)pH值升高雙酚A的光催化降解率均逐漸降低,與TiO_2的趨勢相同。離子強(qiáng)度對于催化劑的光催化降解性能具有一定的抑制作用;且Nano-CuO和CuO/MWCNTs的響應(yīng)基本一致。
[Abstract]:Bisphenol A (BPA) belongs to environmental endocrine disruptors. It is common in the environment. It can be used to reproduce biological or human body by interfering with the synthesis, secretion, transportation, combination, reaction and metabolism of natural hormones. The function of nerve and immune system has an effect. TiO-2 is a photocatalyst with wide application prospect. In recent years, it has been the focus of research at home and abroad. CuO has good chemical stability, acid resistance, alkali resistance, low toxicity and low cost. It is easy to produce in a large industrial scale; but the position of conduction band potential of CuO is corrected compared with that of H 2O reduction potential. The photocatalytic degradation kinetics of bisphenol A was studied by using two different particle sizes of TIO _ 2 / TIO _ (2) O _ (2) O _ (2) TIO _ (2) O _ (2) and carbon nanotube supported CuO as catalysts to study the photocatalytic degradation kinetics of bisphenol A. The photocatalytic properties of the reaction solution under the conditions of pH value, ionic strength and concentration of bisphenol A solution were as follows: the photocatalytic degradation rate of bisphenol A reached equilibrium after 48 h under the action of two kinds of TiO_2. The addition of catalyst and the concentration of bisphenol A both affected the degradation rate of bisphenol A. with the increase of pH value, the degradation rate of bisphenol A was increased with the increase of pH value. The photocatalytic degradation rate of bisphenol A decreased gradually. The ionic strength in the solution inhibited the photocatalytic degradation of bisphenol A. the higher the ionic strength, the more obvious the inhibition effect was. The equilibrium time of photocatalytic degradation of bisphenol A by Nano-CuO and CuO/MWCNTs was 24 h, and the photocatalytic degradation performance of CuO/MWCNTs was significantly higher than that of Nano-CuO and CuO/MWCNTs and the concentration of bisphenol A. With the increase of pH value of electrolyte, the photocatalytic degradation rate of bisphenol A decreased gradually. The ionic strength has a certain inhibitory effect on the photocatalytic degradation of the catalyst, and the response of Nano-CuO and CuO/MWCNTs is basically the same.
