Determinação potenciométrica do boro, solúvel em água, em fertilizantes

This paper deals on the adaptation of the volumetric determination of boron soluble in water in fertilizers, to the potenciometric titration technique, used in the determination of boron soluble in acid, in the same materials. The results allowed to conclude that the method presents suitable precision and accuracy, comparable to the volumetric method basead on the common titration.
