Partitioning of Cu, Pb, Ag, Zn, Fe, Al, and Mn Between Filter-Retained Particles, Colloids, and Solution in 6 Texas Estuaries
(, 1994 Mar)
There are few methodical studies of processes controlling trace metal behavior in estuaries, where river water gradually mixes with seawater leading to systematic changes in ionic strength, pH, DOC, nutrient concentrations, ...
Analysis of biogenic thiols in natural water samples by high-performance liquid chromatographic separation and fluorescence detection with ammonium 7-fluorobenzo-2-oxa-1,3-diazole-4-sulfonate (SBD-F)
(, 2000 Mar 9)
A sensitive and reliable reversed-phase high-performance liquid chromatography (HPLC) method has been developed to analyze naturally occurring low-molecular weight thiols using pre-column derivatization with ammonium ...
The distribution of biogenic thiols in surface waters of Galveston Bay
(, 2000 Sep)
Thiolic compounds are important metal-complexing ligands as well as important components of the global sulfur biogeochemical cycle. A lack of information on the concentration and distribution of thiols in natural waters, ...
Trace metal analysis of natural waters by ICP-MS with on-line preconcentration and ultrasonic nebulization
(, 1999 Feb)
Concentrations of Mn, Ni, Cu, Zn and Pb in natural waters were measured by inductively coupled plasma mass spectrometry (ICP-RIS) with on-line preconcentration using Toyopearl TSK-immobilized 8-hydroxyquinoline resin columns ...
