What is Study of the Coloured Substances in Molybdenum Blue Using High-performance Liquid Chromatography about?
Methods for the separation of reduction products of phosphomolybdate and silicomolybdate were established by high-performance liquid chromatography using Styragel 60 A (Waters Assoc.) as a packed material and acetonitrile solution containing sulphuric acid as an eluent. Reduction products of phosphomolybdate were separated into two species, Product I (P) and Product II (P). Reduction products of silicomolybdate were also separated into two component species, Product I (Si) and Product II (Si). From the investigation of phpsphomolybdenum blue complexes produced via various different colour reactions, it was observed that the molybdenum blue reaction for phosphate proceeded in two stages as follows: H3P04 . 12Mo03 + H3P04 . lOMoO . Moz05 + H3P04 -8Mo03 . 2Moz05. The apparent molar absorptivity of Product I (P) was 7.4 times larger than that of Product II (P). Similarly, the molybdenum blue reaction for silicate was studied and discussed.
