High-frequency measurement of seawater chemistry: Flow-injection analysis of macronutrients
We adapted a commercially available flow-injection autoanalyzer (Lachat Quik-Chem 8000) to measure seawater nitrate concentrations at a rate of nearly 0.1 Hz and phosphate and silicate concentrations at a rate half that. Several minor improvements, including reduced sample-loop size, high sample flushing rate, modified carrier chemistry, and use of peak height rather than peak area as a proxy f...

15 صفحه اولReverse Flow Injection Analysis of Trace Amounts of Anionic Surfactants in Seawater without Liquid–liquid Extraction
In order to control the pollution by anionic surfactants in seawater, a simple, accurate and sensitive reverse flow injection (rFIA) spectrophotometric method for the determination of anionic surfactants in seawater is suggested in this paper. Sodium dodecylbenzenesulfonate (LAS) was selected as the reference anionic surfactant. The method is based on the ion associate formed between LAS and Et...
