Abstract

The relation of direct proportion between absorbance and nanometer grain content is educed by analysing the extinction law which the monochromatic light passes turbid solution of nanometer grain. The feasibility mensurating nanometer grain content for complex material by spectrophotometric method is verified according to the composite deposit of Ni-P/alpha-Al₂O₃ (30nm). The results show that the standard curve of relation between the concentration of turbid solution of nanometer grain and absorbance is a straight line, and the linear correlative degree of the data reaches 99.96%. The measuring condition which the incident light wave is 500nm, and the concentration range of alpha-Al₂O₃ is 8-40mgmiddotL^-1 is determined; moreover, the effect of ultrasonic wave dispersion on absorbency of nanometer particle is also studied. So it offers a better method to mensurate nanometer grain content for complex material
