Morales, Alfonso; Inés Toral, Alfonso (1985)A highly sensitive extraction-spectrophotometric method has been developed for the determination of iron based on the formation of a ternary complex with 1,10-phenanthroline as a primary ligand and picrate as a counter ...
-
Morales, Alfonso; González V., Flora (Elsevier, 1967)The behaviour of uranium in both organic and inorganic supporting electrolytes is examined, and also the influence of complexing agents on the incision in the curve, dE/dt =f(E). The addition of TEA to supporting electrolytes ...

Polarographic behaviour and determination of nitrofurantoin, chloramphenicol and related compounds Morales, Alfonso; Toral Ponce, María; Richter Duk, Pablo (1984)The polarographic behaviour of nitrofurantoin and chloramphenicol have been studied in pyridine - formic acid buffer and tetramethylammonium chloride solution at pH 4.3. The E<inf>1/2</inf> versus pH and iym ...
