【摘要】：我國是染料生產(chǎn)和使用的第一大國,該過程中產(chǎn)生的印染廢水已嚴(yán)重威脅到我國水體安全。由于酸性染料的結(jié)構(gòu)穩(wěn)定,在廢水處理過程中很難被生化方法徹底處理,通常以物理吸附作為處理的主要方法,開發(fā)一種新型高效的吸附劑已成為當(dāng)下的研究熱點(diǎn)。前期本課題組對葫蘆脲吸附性能的研究發(fā)現(xiàn)其具有顯著的吸附性能,本研究應(yīng)用葫蘆脲作為一種高效的吸附劑移除印染廢水中酸性染料以達(dá)到處理印染廢水的目的。研究了葫蘆[6]脲和葫蘆[8]脲對偶氮結(jié)構(gòu)的酸性紅27染料和酸性橙7染料的吸附影響因素、吸附行為和吸附機(jī)理。(1)對酸性紅27染料的吸附研究表明:葫蘆[6]脲對酸性紅27染料的吸附在50min內(nèi)可達(dá)吸附平衡,染料移除率達(dá)80%;溫度的升高不利于吸附反應(yīng)的進(jìn)行;堿性條件促進(jìn)吸附反應(yīng),酸性條件抑制吸附進(jìn)行;金屬離子(K~+,Ga~(2+),Na~+,Mg~(2+)的存在提高了吸附效率。葫蘆[8]脲對酸性紅27染料的吸附更高效,30min內(nèi)可達(dá)吸附平衡,最大吸附量為332.2mg/g,染料移除率高達(dá)99%;升溫不利于吸附反應(yīng)進(jìn)行;堿性條件促進(jìn)吸附反應(yīng),酸性條件抑制吸附反應(yīng);金屬離子(K~+,Ga~(2+),Na~+,Mg~(2+))的存在降低了吸附效率。葫蘆[6]脲和葫蘆[8]脲對酸性紅27染料的吸附符合Langmuir單分子層吸附;吸附是由焓驅(qū)動的放熱反應(yīng);吸附過程符合準(zhǔn)二級動力學(xué)模型,表明在吸附過程中伴隨著化學(xué)鍵的產(chǎn)生;通過紅外光譜和熱重分析證實(shí)了吸附過程中伴隨著新的物相的生成。(2)對酸性橙7染料研究表明:葫蘆[6]脲對酸性橙7染料的吸附在60min內(nèi)可達(dá)吸附平衡,染料移除率為45%;溫度的升高不利于吸附反應(yīng)的進(jìn)行;堿性條件促進(jìn)吸附反應(yīng),酸性條件抑制吸附進(jìn)行;Ga~(2+),Mg~(2+)的存在提高了吸附效率,K~+,Na~+的存在降低吸附效率;其吸附是符合Langmuir吸附等溫方程的單分子層吸附。葫蘆[8]脲對酸性橙7染料的吸附在30min內(nèi)可達(dá)吸附平衡,染料移除率為82%;升溫不利于吸附反應(yīng)進(jìn)行,堿性條件促進(jìn)吸附反應(yīng),酸性條件抑制吸附反應(yīng);金屬離子(K~+,Ga~(2+),Na~+,Mg~(2+))的存在降低了吸附效率;吸附是符合Freundlich等溫方程的多分子層吸附。葫蘆[6]脲和葫蘆[8]脲對酸性橙7染料的吸附過程是由焓驅(qū)動的放熱反應(yīng);吸附過程符合準(zhǔn)二級動力學(xué)模型,伴隨著化學(xué)鍵的產(chǎn)生;通過紅外光譜和熱重分析證實(shí)了吸附過程中有新的物相的生成。研究表明葫蘆脲可以作為吸附印染廢水中酸性染料的高效吸附劑,為課題的深入研究和實(shí)現(xiàn)葫蘆脲在印染廢水處理上的應(yīng)用提供理論指導(dǎo)。
[Abstract]:China is the largest country in the production and use of dyes. The printing and dyeing wastewater produced in this process has seriously threatened the safety of water bodies in China. Because of the stable structure of acid dyes, it is difficult to be thoroughly treated by biochemical methods in the process of wastewater treatment. Usually, physical adsorption is the main method of treatment, and the development of a new and efficient adsorbent has become a hot research topic at present. The previous study on the adsorption properties of gourd urea showed that it had remarkable adsorption performance. In this study, the acid dyes in printing and dyeing wastewater were removed by using gourd urea as an efficient adsorbent to achieve the purpose of treating printing and dyeing wastewater. The adsorption factors of [6] urea and [8] urea for azo acid red 27 dyes and acid orange 7 dyes were studied. The adsorption behavior and adsorption mechanism of acid red 27 dye were studied. The results showed that the adsorption of acid red 27 dye by gourd [6] urea could reach the equilibrium in 50min, the removal rate of dye reached 80%, and the increase of temperature was not conducive to the adsorption reaction. The adsorption efficiency was improved by alkaline condition, acid condition inhibited adsorption, and the presence of metal ion (K ~ (+) K ~ (+) ~ (1) ~ (2) (Na ~ (2) (mg ~ (2) increased the adsorption efficiency. The adsorption equilibrium of gourd [8] urea for acid red 27 dye can be reached within 30 minutes, the maximum adsorption capacity is 332.2 mg / g, the removal rate of dye is as high as 99%, the temperature rise is not conducive to the adsorption reaction, the basic condition promotes the adsorption reaction, the acid condition inhibits the adsorption reaction. The existence of the metal ion K ~ (+) (K ~ (+) decreases the adsorption efficiency of Na ~ (2) (P _ (2) O _ (2). The adsorption of acid red 27 dyes by gourd [6] urea and gourd [8] urea accords with Langmuir monolayer adsorption, the adsorption is an exothermic reaction driven by enthalpy, the adsorption process accords with the quasi-second-order kinetic model, which indicates that the chemical bond is produced during the adsorption process. The results of infrared spectroscopy and thermogravimetric analysis showed that the adsorption of acid orange 7 dyes by cucurbit [6] urea could reach the adsorption equilibrium in 60min with the formation of new phase. The removal rate of dye is 450.The increase of temperature is not conducive to the adsorption reaction, the alkaline condition promotes the adsorption reaction, the acidic condition inhibits the adsorption, and the presence of the acid condition increases the adsorption efficiency and reduces the adsorption efficiency. Its adsorption is monolayer adsorption which accords with Langmuir adsorption isotherm equation. The adsorption of acid orange 7 dye by cucurbita [8] urea can reach the equilibrium in 30min, the removal rate of dye is 822.The temperature rise is not conducive to the adsorption reaction, the basic condition promotes the adsorption reaction, the acid condition inhibits the adsorption reaction. The presence of the metal ion K ~ (2 +) (K ~ +) decreases the adsorption efficiency, and the adsorption is a multilayer adsorption in accordance with the Freundlich isotherm equation. The adsorption process of acid orange 7 dyes by gourd [6] urea and gourd [8] urea is an exothermic reaction driven by enthalpy. Infrared spectroscopy and thermogravimetric analysis confirmed the formation of new phase in the adsorption process. The results show that cucurbituril can be used as an effective adsorbent for the adsorption of acid dyes in printing and dyeing wastewater, which provides theoretical guidance for further research and application of cucurbituron in the treatment of printing and dyeing wastewater.
