The feasibility of Ru as a permanent modi her for the determination of Cd in biological samples treated with TMAH by ET-AAS was investigated [10]. The sample dissolution procedure was very simple a sample aliquot was mixed with a small volume of a 25 percent TMAH solution, the volume was made up to 50 mL and the mixture was kept at 60°C for 1 h. Four biological CRMs (DOLT-2, DORM-1, LUST-1, and TORT-2) were analyzed and the obtained Cd concentrations were within the 95 percent cont>dence interval of the certified values.

Depth profiles of cell densities in the photic zone generally show E. huxleyi to live within the mixed layer. Cortes et al. (2001) studied the seasonal depth distribution of coccohthophorid species off Hawaii. Sampling showed that the main production occurred in the middle photic zone (50-100 m), which lay within the mixed layer for most of the year. While the depth of maximum E. huxleyi density varied during the annual cycle, it generally lay between the shallowest sampling level (10 m) and 100 m. Depth profiles off Bermuda (Haidar and Thierstein, 2001) found that maximum densities of E. huxleyi were nearly always shallower than 100 m, and more commonly within the upper 50 m. The highest cell densities for E. huxleyi recorded were at 1 m depth in March, after the seasonal advection of nitrate into the mixed layer. Seven years of water-column particulate data off Bermuda confirm that alkenone concentrations in the surface mixed layer are 2-4 times higher than in the deep fluorescence maximum at 75-110 m (Conte et al., 2001). 

Introduction.— Having discussed briefly the theory of dissoluti( consider some of the ways in which the dissolution of solids in liqi plished in actual practice. The problem is evidently to bring cont. solution in contact with the solid particles that is, different solution it may not be any less concentrated with the solute than the solution ir a from around the particles still the mere friction of this displacement sex reduce the thickness of the film surrounding it. Therefore it would seen the most efficient way to accomplish this is to move the solid through the sol or the solution through the particles or to move both in opposite direct while in contact with each other.
