由于严格的环境法规，汽油/柴油等液体燃料的超深度脱硫引起了现代清洁燃料研究的相当大的关注。此外，燃烧过程中产生的SO_x还会对催化转化器和排气系统产生毒害作用.与传统的催化和加氢脱硫技术相比，吸附法脱除噻吩衍生物等含硫化合物是一种很有前途的方法，它不需要氢气和高温。在这项研究中，我们使用硫化镍纳米粒子纳入聚（甲基丙烯酸甲酯）-氧化锆膜作为潜在的亲和材料吸附萃取二苯并噻吩从正己烷。利用傅里叶变换红外光谱（FTIR）和原子力显微镜（AFM）对材料的功能性和表面形貌进行了表征。通过监测在环境条件下用合成材料处理之前和之后标准溶液的吸光度值的变化来确定关于二苯并噻吩的吸附去除的定量数据。硫化镍纳米颗粒表现出合适的再结合响应，去除二苯并噻吩下降到1 ppm，由于亲和相互作用，这是有用的关于超深脱硫。最后，硫化镍纳米粒子被纳入到聚（甲基丙烯酸甲酯）-氧化锆膜，这表明在环境条件下的二苯并噻吩的吸附脱硫的潜在应用。
Ultra deep desulfurization of liquid fuels such as gasoline/diesel has attracted considerable attention of modern clean fuel research due to strict environmental regulations. Apart from that, SO_x produced during combustion, poison the catalytic converter and exhaust emission system. Comparing to conventional catalytic and hydrodesulfurization techniques, adsorptive method for removal of sulfur bearing compounds e.g. thiophene derivatives is a promising approach which does not require hydrogen gas and high temperature. In this study, we used nickel sulfide nanoparticles incorporated poly(methyl methacrylate)-zirconia membranes as potential affinity material for adsorptive extraction of dibenzothiophene from n-hexane. The functionality and surface morphology of synthesized material was examined by Fourier transformation infrared (FTIR) spectroscopy and atomic force microscopy (AFM) images, respectively. The quantitative data regarding adsorptive removal of dibenzothiophene was determined by monitoring the shift in absorbance values of standard solutions before and after treating with synthesized material under ambient conditions. Nickel sulphide nanoparticles exhibited suitable rebinding response for removal of dibenzothiophene down to 1 ppm due to affinity interactions which is useful concerning ultra deep desulfurization. Finally, nickel sulphide nanoparticles were incorporated in poly(methyl methacrylate)-zirconia membrane which showed potential application for adsorptive desulfurization of dibenzothiophene at ambient conditions.
