In this paper, the hazardous wastes were comprehensively investigated with scanning electron microscopy (SEM) and X-ray diffraction (XRD). It is found that the chemical compositions of these wastes are very complicated. A variety of fluoride salts and aluminum metal were embedded in pores and ...

describes wastes that are “characterized as hazardous under Article 1 paragraph 1 (a) of the Convention” although the “designation of a waste on Annex VIII does not preclude the use of Annex III (hazard characteristics) to demonstrate that a waste is not hazardous” (Annex I, paragraph (...
For transforming or degrading chemicals, the magnitude of contamination depends on the residence time in the unsaturated zone. The residence time is dependent on chemical and soil characteristics and meteorologic conditions. The movement of hazardous wastes or pesticides is inherently affected by soil ...
The Toxicity Characteristic Leaching Procedure (TCLP) is used by the United States Environmental Protection Agency to determine if wastes contain extractable components subject to hazardous waste regulations. This paper examines the limitations of the TCLP and the way it is used by studying a particular...
The results showed that solidification ratio could well represent the solidification efficiency of heavy metals in different temperature phases during melting process. According to the Identification Standard for Hazardous Wastes in China and USA, melting residues of fly ash is not classified as hazardous...
METHOD 1311 TOXICITY CHARACTERISTIC LEACHING PROCEDURE 1.0 SCOPE AND APPLICATION 1.1 The TCLP is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid, and multiphasic wastes. 1.2 If a total analysis of the waste demonstrates that individual analytes are ...
1.4 If an analysis of extract obtained using a bottle extractor shows that the concentration of any regulated volatile analyte exceeds the regulatory level for that compound, then the waste is hazardous and extraction using the ZHE is not necessary. However, extract from a bottle extractor cannot ...
The generation characteristics of hazardous wastes are summarized as six characteristics including the complexity of their generators, the orderliness of their quantities, the multiplicity of their categories, the control of their treatment, the disequilibrium of their area distributing, the relevancy. 通...
