In recent years, kitchen oily wastewater has received much attention because of its harmful effects on the ecol. environment. Therefore, separation of oil from kitchen oily wastewater has become an urgent issue. In this study, this problem could be solved using polyester fabrics covered with cupric hydroxide and cellulose. The functional fabric was obtained by the dipping-rolling-drying process which is an easy and practical way to prepare the fabric and could improve the hydrophilicity of polyester. The functional polyester fabric could sep. oil/water mixtures completely under the force of gravity with a high water flux of 2079 L m-2 h-1-3620 L m-2 h-1 and high separation efficiency of 99.6%. Because kitchen oily wastewater contains floating oil and emulsified oil, we also tested the separation of oil-in-water emulsions. The functional polyester fabric could successfully sep. the emulsions with the water flux of 1210 L m-2 h-1-2018 L m-2 h-1 and a separation efficiency of 99.0%. Moreover, the water flux and separation efficiency of functional polyester fabric remained unchanged after the immersion in salt, alkali, and acid solutions, indicating that the functional polyester fabric exhibited commendable environmental stability. The oil in Chongqing Street Noodles soup with a high oil content was separated to simulate real-life oil/water separation, confirming that the functional polyester fabric could be applied to the treatment of kitchen oily wastewater. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Computed Properties of CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Computed Properties of CuH2O2
