style=\"color:red\">浸出</span>毒性超出TCLP标准规定限值的119和1063倍,<span style=\"color:red\">浸出</span>率分别为47.66%和50.15%.砷以酸可提取态和可还原态为主,两者共占90%左右,而稳定的残渣态含量相对较低,这是含砷石灰铁盐渣<span style=\"color:red\">浸出</span>毒性大、环境活性高的直接原因.本研究为含砷石灰铁盐渣无害化处理技术提供了大量有用的基本数据.","authors":[{"authorName":"彭兵","id":"28d0ce11-bf27-4313-ac5e-139641220c71","originalAuthorName":"彭兵"},{"authorName":"雷杰","id":"4322a5e3-7f29-4a81-b93b-753eb2260070","originalAuthorName":"雷杰"},{"authorName":"闵小波","id":"845264e4-77e8-4521-9e17-a21626ba527f","originalAuthorName":"闵小波"},{"authorName":"柴立元","id":"b7f73125-c659-4471-b4fe-1c5951d05309","originalAuthorName":"柴立元"},{"authorName":"梁彦杰","id":"494d1f1c-6fb2-4acd-a54e-d7b3c794cb19","originalAuthorName":"梁彦杰"},{"authorName":"游洋","id":"3eb9809e-a95e-44f1-bead-10572168ad8d","originalAuthorName":"游洋"}],"doi":"10.1016/S1003-6326(17)60140-7","fpage":"1188","id":"ed7ee6c5-ea12-4db1-b1d6-47dfdd85bd72","issue":"5","journal":{"abbrevTitle":"ZGYSJSXBEN","coverImgSrc":"journal/img/cover/ZGYSJSXBEN.jpg","id":"757390d2-7d95-4517-96f1-e467ce1bff63","issnPpub":"1003-6326","publisherId":"ZGYSJSXBEN","title":"中国有色金属学报(英文版)"},"keywords":[{"id":"ae8ee2c8-e605-4867-a6c4-5806f4f82896","keyword":"含砷固废","originalKeyword":"含砷固废"},{"id":"2eb877f2-90c4-4fa1-b45d-236545fce686","keyword":"石灰铁盐渣","originalKeyword":"石灰铁盐渣"},{"id":"3519c336-7735-4264-9e59-c4eb83274558","keyword":"理化<span
