Potential contributions of clay minerals and organic matter to pentachlorophenol retention in soils 总被引:1,自引:0,他引:1
Sorption of pentachlorophenol (PCP) by pure minerals and humic acids were measured to obtain additional perspective on the potential contributions of both clay minerals and soil organic matter (SOM) to contaminants retention in soils. Four types of common soil minerals and two kinds of humic acids (HAs) were tested. The sorption affinity for PCP conformed to an order of HAs > K-montmorillonite > Ca-montmorillonite > goethite > kaolinite. Such a difference in sorption capacity could be attributed to the crucial control of HAs. Clay minerals also had their contribution, especially K-montmorillonite, which played an important, if not dominant, role in the controlling process of PCP sorption. By removing 80% (on average) of the organic carbon from the soils with H(2)O(2), the sorption decreased by an average of 50%. The sorption reversibility had been greatly favored as well. Considering the uncharged mineral fractions in soil before and after H(2)O(2)-treated, the main variation in sorption behavior of the soil might thus be related to the removed organic carbon and the reduced pH. This testified rightly the interactive effect of SOM and clay minerals on PCP sorption as a function of pH. 相似文献

The lack of emergency preparedness in Mauritius has been the cause of many tragedies. Our approach to tackle this problem was by developing an emergency preparedness game layered and fused with a disaster warning and guidance system that emanates clarity to the unfathomable bearings of emergencies and natural disasters. The emergency preparedness game is based on a selection of diverse real life-threatening difficulties that entail different strategies aimed at bettering the survival instincts of users. It uses story-telling scenarios along with in-game footnotes that yield directives on how to brave fierce and unpredictable calamities. The game reinforces a sense of self-composedness and suppressing untimely fears of users in horrendous circumstances. With regard to the warning system, it unremittingly feeds users with notifications during emergencies, that encases shortest escape routes to lead them to safe locations via a fully functional GPS map. This application brings some novelties that are virtually non-existent in related applications. For instance, this application includes a warning and guidance system, a 3D scenario game to prepare its users for disasters, an interactive survival toolkit selection, an SMS rescue feature and a mass notification system via the web. 相似文献
