Abstract
A study of both zirconium and hafnium alpha-hydroxycarboxylates for analytical applications is presented, These compounds are studied by infrared spectroscopy, thermal analysis and X-ray diffractometry. dl-Mandelic, dl-p-bromomandelic and dl-2-naphthylglycolic acids are the more adequate reagents for gravimetric determinations of zirconium and hafnium, the ligands dl-2-hydroxyhexanoic and dl-2-hydroxydodecanoic acids were used for the first time and the results showed that they are also adequate reagents for the same purpose.
