Introduction In recent years,with the rapid development of the research and application of nano science and technology, in theprocess of production,research, circulation, application and abandon, nanomaterials inevitably release into the environment, which has becomeone of the important component of environmental pollutants.[1-3]At the same time,the potential environmental and human risks for exposure to nanpmaterials will increase as the quantity and types of nanoparticles used grow.[4]Compared with conventional materials, the specific surface area of nanomaterials enlargesmillions of times, which produce remarkable influences on the particles activity, viscosity, solubility, adsorption, catalysis and application.In terms of environment, with the significant increase in specific surface area of particles, the surface effects, such as surface activity, surface adsorption and catalytic ability are enhanced obviously, which makes the nanoparticles have a strong ability to bind andtransport
Surface area of the particles can impact on the performance of products in many ways, such as paint hiding power , the activity of catalysts, food taste and texture, bioavailability and drug toxicity, etc.[10]At present, there being a lot of physical and chemical methods can implementdetermination of specific surface area of powdered materials.[11]These include gas adsorption (BET method), estimation from particle size distribution data and titration, etc.Gas adsorption method is currently the most widely used for finely divided and porous solids and the most common form of this technique is the BET method.[12, 13]But this method is only used for the determination of dry powders and requests samples to be initially degassed to remove material adsorbed on the particle surface, and the key is that nitrogen (N2) gas is adsorbed on a sample kept at liquid N2 temperature at a series of different pressures,[14] the entire process takes several hours.
