Various extracting agents were used to conduct leaching experiments for desulfurization ashes. The dissolution of trace elements contained in the ashes were determined in order to estimate the possible impacts of the materials for stacking, back-filling or road-paving on the under-ground water and the environment and to assess the possibility of contamination of the sites by release of these ions. The alkalinity greatly determines the ion concentration in leaching liquids. It appears that the risk pollution of ground water as well as of surface water may not be avoidable if the ash alone is used for stacking et al. Nevertheless heavy metal contents of three samples in the leaching solution are far below the specified value regulated in ¿Identification standards for hazardous waste - Identification for extraction toxicity¿(GB5085.3-2007, in China).","PeriodicalId":6348,"journal":{"name":"2009 International Conference on Energy and Environment Technology","volume":"153 1","pages":"616-619"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77121979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that pH played a major role in the adsorption process, the optimum pH for the removal of Pb(II) was 6.0. SEM images showed that the surfaces of particles was rough and irregular with large area for metal-surface interaction, the FTIR spectra showed carboxyl , hydroxyl and amino groups of the PS-2 were involved in chemical interaction with the Pb(II) ions. Equilibrium studies showed that Pb(II) adsorption data followed Langmuir model. The maximum adsorption capacity (qmax) for Pb(II) ions was estimated to be 94.58 mg/g.

The basic configuration of the new topology and its fundamental principle are firstly introduced, the analytic expression on the function of voltage transfer ratio and duty cycle is analyzed, and the rationale of double-loop control strategy is clarified. Finally the validity and feasibility of the new topology are tested by means of computer simulation and prototype experiment. The results indicate that the regulation of the voltage transfer ratio and of the output frequency can be adequately implemented by these new converters with low harmonic distortions of waveform. This study suggests that the problem of low voltage transfer ratio, which has been an inherent drawback of the traditional MCs, can be effectively overcome, and the approach may provide inspiration for further engineering application.","PeriodicalId":6348,"journal":{"name":"2009 International Conference on Energy and Environment Technology","volume":"14 1","pages":"332-336"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81868392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
