Synthesis and aggregation stability of europium oxohydroxide hydrosols

Resumo

Europium oxohydroxide hydrosols that are resistant to aggregation have been obtained by the condensation method. The density of dispersed phase particles, phase composition and dispersity of the sols, electrokinetic potential of the particles, and its dependence on medium pH have been determined. The effect of dispersion medium pH on the mechanism and reversibility of particle aggregation has been studied. The nature of the aggregation stability of the synthesized europium oxohydroxide hydrosols has been discussed.
