Abstract

BACKGROUND

Printing and dyeing reverse osmosis concentrates (ROC) contain large amounts of salts and organic matter, which is a major environmental issue. The unique composition of such wastewater makes the use of traditional physicochemical techniques challenging.

RESULTS

In this paper, titanium dioxide nanotube arrays/SnO₂-Sb₂O₃ (Ti-NTA/SnO₂-Sb₂O₃) electrodes were prepared by anodizing–cathodizing and sol–gel method for the electrocatalytic degradation of printing and dyeing ROC. Organic matter removal under different situations was examined, and the best treatment parameters were identified.

CONCLUSION

Following treatment, organic matter concentration dropped from 1600 to 50 mg L⁻¹, or even less. The outstanding removal performance of the Ti-NTA/SnO₂-Sb₂O₃ electrode was validated by full-scan ultraviolet spectra, gas chromatography–mass spectrometry and three-dimensional fluorescence. Evaluation of the dissolved heavy metals and halogenated degradation process byproducts revealed that the electrocatalytic membranes were environmentally safe. These findings highlight the enormous potential of electrocatalytic membranes for the treatment of high-salt ROC when equipped with a Ti-NTA/SnO₂-Sb₂O₃ electrode. © 2024 Society of Chemical Industry (SCI).

Ti-NTA/SnO2-Sb2O3电催化膜对印染反渗透浓缩液的高效处理

印染反渗透浓缩液中含有大量的盐和有机物，是一个严重的环境问题。这种废水的独特成分使得传统的物理化学技术的使用具有挑战性。结果采用阳极-阴极和溶胶-凝胶法制备了二氧化钛纳米管阵列/SnO2-Sb2O3 （Ti-NTA/SnO2-Sb2O3）电极，用于电催化降解印染ROC。考察了不同条件下的有机物去除率，确定了最佳处理参数。结论处理后，有机物浓度从1600 mg L−1下降到50 mg L−1，甚至更低。通过全扫描紫外光谱、气相色谱-质谱联用以及三维荧光等手段验证了Ti-NTA/SnO2-Sb2O3电极的优异去除性能。对电催化膜中溶解的重金属和降解副产物卤化的评价表明，电催化膜对环境是安全的。这些发现强调了电催化膜在配备Ti-NTA/SnO2-Sb2O3电极时处理高盐ROC的巨大潜力。©2024化学工业学会（SCI）。
