The optimized FI-manifold was used with the Griess method for the spectrophotometric assay of nitrosyl (nitrite) in standards prepared in the matrix of concentrated sulphuric acid (detection limit 0.16 mg/1 NO+-N (3[sgrave])) and in practical WSA-samples.doi:10.1080/00032719808005295...
Citric acid traps to replace sulphuric acid in the ammonia diffusion of dilute water samples for N-15 analysis The analysis of N-15 in aqueous samples requires the concentration of dissolved nitrogen (N) into a small volume that can be analysed by mass spectrometry... Schleppi,P,Bucher-Wallin...

Continuous dilution of sulphuric acid solns - using in line jet mixer to precipitate soluteSolns. of cpds. in conc. H2SO4 are recovered by diluting the acid to precipitate the solute and then filtering. The dilution is carried out continuously in an in-line jet mixer, which acts as a ...
Using vapour rinsing, dilution ratios were measured as functions of rinsing time for carry-over films of sulphuric acid (simulating pickle drag-out) and sodium hydroxide (cleaner drag-out). Sulphuric acid films were diluted very quickly in unstirred rinse water, and also in solutions of sodium ...
