Quantitative Determination of Slightly Soluble Salts by Means of Ion Exchange
TLDR
An ion exchange method for the quantitative determination of slightly soluble salts has been described, requiring little technical skill on the part of the operator and permits a considerable saving of time.Abstract:
An ion exchange method for the quantitative determination of slightly soluble salts has been described. The procedure, which has been aplied to a number of chemicals and to two tablet preparations, gives reproducigle and reliable results. It has the further advantage of requiring little technical skill on the part of the operator and permits a considerable saving of time.read more

Anion determination in damage layers of stone monuments
G. Gobbi,G. Zappia,C. Sabbioni +2 more
TL;DR: In this paper, an analytical procedure was set up for the dissolution of damage layers from stone monuments with the aim of performing ion chromatography analyses, which was performed using ion exchange resin H-form and two serial detectors (conductometer and spectrophotometer).

Alkalimetric titration of phosphoric acid and phosphates
TL;DR: In this paper, a method of removing the disturbing metallic ions with the aid of a cation exchanger was found to be the solution, but without ultimate success, to exclude disturbing fluoride and silicofluoride.
