Creator:: Pequegnat, John Eugene
Abstract:: Short-term changes in the distribution, surface to 10 meters, of phytoplankton-associated trace metals (Fe, Mn, Cr, Zn, Co, Ni, and Cu) were studied in the near-shore waters off Humboldt Bay, California, through the summer of 1971. The depth distribution of phytoplankton-associated trace metals was related to local hydrography. During periods...

Full Text:: . There are numerous studies of trace element concentrations in sea water (Cooper, 1948; Harvey, 1949

Creator:: Ambrose, Arthur Sigurd
Abstract:: An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...

Full Text:: : Development of Trace Enrichment Techniques for Trace Metals in Natural Waters Using High Pressure Liquid

Creator:: Liu, Yan
Abstract:: An automated on-line ion exchange trace enrichment system has been developed to improve the detection limits of flame atomic absorption (AA) spectrophotometry in the determination of trace metals in natural waters. The sample solution is passed through a column of Chelex-100 chelating resin by a carrier buffer stream delivered from...
