Dissolved silica can coprecipitate with zinc from seawater or distilled water that has been enriched with both elements. More than 2 ppm Si are necessary for the reaction to begin. The coprecipitation shows pH dependence. The addition of pulverized illite or natural sediment as suspended particulate material does not enhance the reaction in seawater. The organic material present in the nearshore seawater samples decreases the rate and extent of reaction, as indicated by comparisons of results of experiments using natural seawater with results obtained using UV-irradiated seawater. In unbuffered distilled water the reaction must compete with hydrolysis of zinc; however, reaction does occur, which indicates that the seawater matrix is not essential for the reaction. The coprecipitation can limit the concentration of zinc in seawater to less than the solubility concentration assumed for ZnCO3 or Zn(OH)2. The results suggest that a zinc silicate can precipitate directly from seawater or interstitial water as an authigenic mineral. 相似文献

Suction-induced seepage is pivotal to the installation of caisson foundations in sand. Indeed, the upward pore water flow on the inner side of the caisson wall causes a release of a fraction of soil resistance due to the reduction of the lateral effective stress. A safe caisson installation requires a reliable prediction of soil conditions, especially soil resistance and critical suction for piping. These soil conditions must be predicted for the whole installation process.In this paper, we examine the effect on such prediction of the assumed permeability profile, which is described as a function of depth below the mudline. This study is motivated by the fact that marine sediments generally exhibit a permeability that decreases with depth because of consolidation under gravity. Hence, the question is whether conventional theories based on a constant permeability lead to a conservative prediction of soil conditions or not. Our conclusion is affirmative only regarding piping condition. As for soil resistance, a prediction based on the assumption of a constant permeability is non-conservative. This is due to an overestimated reduction in effective stresses under suction-induced seepage. 相似文献

The tendency of dimethylsulfide (DMS) to form complexes with heavy metal ions in aqueous solutions and the factors that influence
it have been investigated. Among five heavy metal ions examined (Cu2+, Cd2+, Zn2+, Pb2+ and Hg2+), only Hg2+ bound significantly with DMS in aqueous solutions in which Hg2+ concentration was increased to much higher levels than that of natural seawater. The complexation capacity of Hg2+ for DMS was influenced by pH and media. The affinity of Hg2+ for DMS was generally lower at high than at low pH, presumably due to the competition of hydroxide ion to form hydroxomercury
species. In different solutions, the affinity of Hg2+ for DMS followed the following sequence: ultra-purified water > 35‰ NaCl solution > seawater. It seems apparent that chloride
had a negative impact on the complexation of DMS by Hg2+, owing to the competition of chloride with DMS for complexing Hg2+. In addition, the affinity of Hg2+ for DMS in the bulk seawater appeared to be higher than that in the surface microlayer seawater. The tendency of Hg2+ to form complexes with DMS in aqueous solution can be reduced by the presence of 2 mM amino-acid such as glycine, alanine,
serine and cysteine, as these ligands give stable mercury complexes. However, the presence of 2 mM acetate in experimental
solutions had no significant effect on the complexation of Hg2+ with DMS, even though this ligand has a relatively strong complexing capacity for Hg2+. Although mercury ions appeared to have a strong affinity for DMS, the concentration of mercury in seawater is too low to
produce a great effect on the distribution of DMS in oceans. 相似文献

Study of colloidal phosphorus variation in estuary with salinity 总被引：1，自引：0，他引：1
The variation of colloidal phosphorus with salinity in estuary was studied in this paper, which was
compared with those of particle and truly dissolved phosphorus with the purpose of ˉnding out the
similarities and di?erences between their behaviors in the estuary. Distribution patterns of phospho-
rus in particle, colloidal and truly dissolved phase at di?erent salinities and their relationships with
suspended particulate matter were also studied to understand the transformation and transporta-
tion of colloidal phosphorus in estuarine area. The result showed that the concentrations of total
colloidal phosphorus, organic colloidal phosphorus and inorganic colloidall phosphate all descended
from river-end to sea-end, illustrating their terrigenous source. Ratios of organic to total colloidal
phosphorus decreased with salinity's increment, indicating that organic phosphorus was in°uenced
by scavenging process of colloid more signiˉcantly as compared with inorganic phosphate. Both of
the phosphorus variation tendencies and the proportion between organic and inorganic phosphorus
in colloidal phase was similar with that in truly dissolved phase while di?erent from that in particle
phase. 相似文献

In connection with global warming, the growth in the intensity of tropical hurricanes is predicted. The onset of this intensification is partially illustrated by the western Atlantic cyclonic zone [1]. It is noted in [1]that, due to global warming, the sea-surface temperature (SST) over the entire world has increased by 0.6°C since 1970. Since the SST basically determines the energy of tropical hurricanes, it is inferred that global warming will lead to an enhancement in their intensity. This publication presents a plot of the dynamics of SST annual mean anomalies for the northwestern Atlantic and pays special attention to significant excess mean temperatures since 1994. The anomalies are determined with respect to the mean temperature calculated from SSTs over 1901–1970. The same plot also shows that the SST at the end of the 1940s and during the 1950s exceeded the mean temperature by about 0.3 or even 0.4°C, decreasing gradually to negative anomalies (?0.3°C) in 1973. After that, the temperature started to increase again. Figure 1 shows a detail of this plot, which relates to the period 1950–2000. 相似文献
