Single-Microparticle Injection and Microabsorptiometry: Direct Analysis of Sorption Processes.
Sorption processes of methylene blue in a single silica gel microparticle in an aqueous solution was kinetically analyzed by a new technique combined with the microcapillary injection/manipulation and microabsorptiometry of the single particle. The observed sorption rates were analyzed in terms of the solute concentration in water and the particle size. The sorption processes were governed by diffusion of the solute in the particle.
