Abstract

The optical characteristics (the diffuse reflection and transmission coefficients, direct transmission coefficient) of the aqueous suspensions of various ultra-disperse diamonds (UDD) modifications have been investigated at the single light scattering conditions coefficient at the range of 300 - 700 nm. The spectra of the absorption and scattering coefficients were calculated. Analysis of the obtained spectra of the absorption coefficients permits to identify the absorption bands because of presence of the different carbon forms (graphite, soot), haematite, etc. and to determine their quantitative contents. The sizes of UDD aggregates in aqueous suspensions were estimated by the using of the scattering coefficient spectra. Obtained results are evident on efficiency of the optical methods of application for assessment of the surface chemistry of the UDD.
