Organic complexation of copper in surface waters of Galveston Bay
(, 2001 Mar)
The importance of colloidal ligands in the organic complexation of Cu was elucidated in the estuarine waters of Galveston Bay by use of a number of instrumental techniques. Ultrafiltration was conducted to isolate the ...
Nitrogen and carbon isotopic composition of high-molecular-weight dissolved organic matter in marine environments
High-molecular-weight (HMW) dissolved organic matter (DOM) was isolated using cross-flow ultrafiltration from seawater across a salinity gradient in 2 estuarine/coastal marine environments-Chesapeake Bay/Middle Atlantic ...
An ultraclean cross-flow ultrafiltration technique for the study of trace metal phase speciation in seawater
(, 1996 Nov)
A series of laboratory and field studies were conducted to test suitability and optimal sampling conditions of an Amicon ultrafiltration system for the collection of colloidal material for trace metal phase speciation ...
Fibrillar polysaccharides in marine macromolecular organic matter as imaged by atomic force microscopy and transmission electron microscopy
(, 1998 Jul)
A consensus is now emerging that the structure of organic macromolecules will determine their function in aquatic systems. Transmission electron microscopy (TEM) is a widely used technique to study the morphology of ...
