Preparation of attapulgite nanoparticles modified polypropylene adsorption membrane and its application in small molecular pollutant adsorption
In this study, a novel surface covalent reaction method was used to modify attapulgite nanoparticles on the surface of polypropylene adsorption membrane to adsorb various small molecular pollutants for the first time. The surface covalent reaction method has the advantage of step control. Therefore, the uniformity and stability of attapulgite nanoparticles can be ensured, and then could effectively improve the adsorption performance of polypropylene adsorption membrane. On the other hand, compared with various materials modified on the surface of polypropylene adsorption membrane currently, attapulgite nanoparticles has the characteristics of low cost and environmental friendliness, which is more conducive to the large-scale practical application. The polypropylene adsorption membrane modified with attapulgite nanoparticles was characterized by field emission scanning electron microscopy, fourier transform infrared spectrometer and X-ray diffractograph, and it was confirmed that the attapulgite nanoparticles was successfully modified on the surface of the polypropylene adsorption membrane. The experimental results showed that the adsorption capacities of polypropylene adsorption membrane modified with attapulgite nanoparticles could reach 11.53 mg/g, 8.7 mg/g and 5.78 mg/g for cyromazine, malachite green and dagenan respectively within 10 s. In the case of the above three analytes, the minimum detected concentration could reach 0.02 mg/mL, and the relative standard deviation was about 10 %. At the same time, the adsorption performance of polypropylene adsorption membrane modified with attapulgite nanoparticles did not decrease significantly after 50 cycles. A standard recovery of 76.8 % − 89.5 % and a relative standard deviation of 7.2 % − 15.2 % were obtained by using the polypropylene adsorption membrane modified with attapulgite nanoparticles to adsorb cyromazine in cucumber skin samples, indicating that the polypropylene adsorption membrane modified with attapulgite nanoparticles has the ability to treat complex samples.
