Coal combustion by-products (CCPs) (i.e. fly (FA) and bottom (BA) ashes) generated by power plants contain heavy metals. This research presents leaching properties of coal ashes (FA and BA) collected from Jimah coal-fired power station, Port Dickson, Negeri Sembilan using USEPA standard methods namely toxicity characteristic leaching procedure (TCLP), and synthetic precipitation leaching procedure (SPLP). Heavy metals like lead (Pb), zinc (Zn), copper (Cu) and arsenic (As) were quantified using atomic absorption spectrometer (AAS). The leached of heavy metals fluxes were Cu < Zn < Pb < As. As leached the most whilst indicating of possible contamination from As. Overall, the ranges of leached concentration were adhered to permissible limits of hazardous waste criteria for metal (Pb and As) and industrial effluent (Zn and Cu). The presented data has potential reuse as reference for the coal ash concrete mixed design application in construction industries.
发电厂产生的煤燃烧副产品（CCPs）（即飞灰（FA）和底灰（BA））含有重金属。本研究采用美国环境保护局（USEPA）的标准方法，即毒性特征浸出程序（TCLP）和合成沉淀浸出程序（SPLP），介绍了从森美兰州波德申的吉马燃煤电站收集的煤灰（FA和BA）的浸出特性。使用原子吸收光谱仪（AAS）对铅（Pb）、锌（Zn）、铜（Cu）和砷（As）等重金属进行了定量分析。重金属的浸出通量顺序为Cu < Zn < Pb < As。砷的浸出量最大，表明可能存在砷污染。总体而言，浸出浓度范围符合金属（铅和砷）危险废物标准以及工业废水（锌和铜）的允许限值。所呈现的数据具有潜在的再利用价值，可为建筑行业的煤灰混凝土配合比设计应用提供参考。
