A series of novel fluoropolymer anion exchange membranes based on the copolymer of vinylbenzyl chloride, butyl methacrylate, and hexafluorobutyl methacrylate has been prepared. Fourier transform infrared (FT-IR) spectroscopy and elemental analysis techniques are used to study the chemical structure and chemical composition of the membranes. The water(More)
To model foamy-oil flow in the development of heavy oil reservoirs, three depletion experiments were conducted with foamy oil treated as a pseudo-single-phase flow. In this pseudo single phase, dispersed bubbles are viewed as a part of the oil, and the redefined effective permeability varies with the changes of pressure depletion rate, oil viscosity, and(More)
The rare elements may have positive effects on growth of plants, and they are the beneficial elements to plants. Lead is one of heavy metals which are harmful to plants and human body. In this paper, the effect of lanthanum on lead absorption in soybean seedling were researched by water culture. Lead in soybean seedling was measured by AAS. The experimental(More)
