The review concentrates on wastewaters from the metalplating industry. The applicability of electrodeposition has been greatly improved through the development of large surface area electrodes. Electrodeposition now appears to be a promising treatment method, especially for wastewaters that contain heavy metals ions in fairly high concentrations together with chelating agents. Water evaporation techniques and adsorption on insoluble starch xanthate are promising developments that merit attention. Heavy metals sulfide precipitation by adding compounds like FeS and CaS seems to be an improvement in comparison to older methods in which soluble sulfides were added. Ways to separate different species of heavy metals ions from each other by means of combined ion exchange and hydrometallurgical extraction may be of interest in situations were the wastewaters from many firms are treated in one central processing plant. Progress in membrane processes is to be expected as the quality of membranes steadily improves. Several other novel and interesting removal methods have been proposed such as e.g. electroprecipitation and the reduction of chromates with sulfides and ferrous ions.</p></div>","PeriodicalId":101079,"journal":{"name":"Resources and Conservation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0166-3097(87)90013-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88151483","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}

The large variety of natural and man made products ending up as household waste contributes significantly to the extreme heterogeneous composition of the material under investigation. Thus, sampling and sample preparation may be considered to be the crucial step of any analysis of waste. To meet the statistical requirements as well as the existing possibilities of the investigating laboratory, a practicable approach has to be found. It is shown that the reported preparation technique, including sorting and classifying of the bulk sample into material categories followed by a three step crushing and grinding procedure, is a reasonable solution. Frequently used analyses methods for heavy metals, such as atomic absorption spectrometry (AAS) and X-ray fluorescence spectrometry (XRF) are reported after the description of wet decomposition techniques as well as plasma dry-ashing of the sample. For the determination of chlorine, fluorine and sulphur in waste, the Wickbold oxygen-hydrogen-flame decomposition technique is recommend in combination with ionchromatography. Additionally, basic principles and methods for emissions measurements are summarized. To illustrate the broad range of analytical tools applied, a newly developed dust emission monitor is reported as well as the use of IR-LASER-spectrometry for continuous measuring of HF in the flue gas. Finally, the determination of polychlorinated dioxins (PCDD) in fly ash is mentioned as a prominent example of complex ultra trace analysis.</p></div>","PeriodicalId":101079,"journal":{"name":"Resources and Conservation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0166-3097(87)90023-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81716979","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}
