Surface mass transfer processes during colour removal from effluent using silica
TL;DR: In this article, the effects of several variables on the initial rate of Astrazone Blue (Basic) dye removal have been investigated and the surface mass transfer coefficients have been determined and correlated as the dimensionless mass transfer term Sh/Sc 0.33, as a function of agitation, initial dye concentration, silica particle size and temperature.
