摘要:

通过硝酸(HNO3)实现两亲性三聚氰胺海绵(MS)的一步式协同超疏水改性, 从而得到了一种具有优异性能的油水分离材料——硝酸改性三聚氰胺海绵(HMMS). 采用傅里叶变换红外光谱(FTIR)、 热重(TG)和扫描电子显微镜(SEM)对HMMS的结构、 形貌和组分进行了表征, 并对其表面润湿性、 机械性能、 吸附性能和油水分离性能等进行了研究. 结果表明, HMMS具有超疏水性, 以及优异的机械性能、 循环使用能力、 选择性吸附能力, 对油水混合物的连续分离效率可达6×10 6 L?m -3?h -1, 并且可在苛刻的使用环境中保持稳定的物理化学性质.

Abstract:

The amphiphilic melamine sponge(MS) was synergistically modified in one step by nitric acid(HNO3). Thus, the HNO3 modified melamine sponge(HMMS) with superhydrophobicity was prepared. The structure, morphology and composition of the prepared HMMS were analyzed by Fourier transform infra-red spectroscopy(FTIR), thermogravimetry(TG) and scanning electron microscopy(SEM). And its surface wettability, mechanical properties, adsorption properties, recycling performance and oil-water separation perfor-mance were studied. The results show that the HMMS has superhydrophobicity, excellent mechanical properties, recycling ability and selective adsorption capacity, and exhibits high separation efficiency up to 6×10 6 L?m -3?h -1. Particularly, HMMS can remain stable in physicochemical properties in demanding environments. Therefore, the novel oil-water separation material have high practical application value.

Key words: Melamine sponge, Oil-water separation, Adsorption property, Surface modification, Superhydrophobicity
