文摘
- •
An advanced oxidative process is implemented in a flow analyzer.
- •
Sulphate radicals are in-line generated by peroxymonosulfate activation by Co(II).
- •
Fertilizer samples are in-line analysed for phosphite and phosphate.
- •
Analytical curves are obtained by in-line dilutions of a single standard solution.
- •
Good figures of analytical merit are attained.
