Abstract

With the rapid development of the modern petroleum industry, coal oil and fine chemical industry, the problem of water pollution caused by organic matter (oil) is becoming increasingly serious, which is one of the main factors restricting the construction of ecological civilization in China. With its good adsorption properties, attapulgite has become a natural, low-cost and efficient adsorption material for water pollution management. The multiple pore-making agents and the principle of hard templates were used to overcome the problem of easy agglomeration of nano-sized rod crystals, and the adsorption rate of the produced attapulgite-based porous material (SA) was greatly increased. The SA materials were modified by silane coupling agent modification technology and chemical vapor deposition (CVD), and the resulting attapulgite-based porous hydrophobic materials (HSAs) were low-cost, easy to recycle, and possessed porous, lipophilic and hydrophobic properties. The HSA was characterized by characterization techniques such as XRD, SEM, BET, XPS and UV spectral analysis. The experimental results showed that the HSA not only exhibited super lipophilic and hydrophobic properties but also excelled in the adsorption capacity of organic pollutants, as well as showed high selectivity in the water/organic matter (oil) separation process.

Key words： attapulgite-based porous material hydrophobic modification selective adsorption
