    • A method of asbestos detoxification in which an asbestos-containing waste material in any form is made harmless while preventing asbestos particles or dust from flying or scattering. The asbestos content can be easily reduced in a short time to 0.1 wt. % or lower, which is prescribed by the Ministry of Health, Labor, and Welfare. The waste can be perfectly made harmless. Also provided is an aqueous solution for asbestos detoxification which is for use in the method. The method of asbestos detoxification comprises: bringing an asbestos-containing waste material into contact with an aqueous treating solution containing at least one fluoride ion source selected from the group consisting of the fluorides of alkali metals, alkaline earth metals, and ammonia and hydrofluoric acid and further containing at least one mineral acid selected from the group consisting of hydrochloric acid, sulfuric acid, and nitric acid so that the aqueous treating solution has a pH of 1 or lower; and allowing the resultant mixture to stand or stirring it while adding the mineral acid so as to keep the pH of the aqueous treating solution at 1 or lower. Thus, the asbestos in the asbestos-containing waste material is made harmless.
    • 一种石棉解毒方法,其中任何形式的含石棉废料在防止石棉颗粒或灰尘飞散或飞散时都是无害的。 石棉含量可以在短时间内容易地降低到0.1wt。 %或以下,由卫生,劳动和福利部规定。 废物可以完美无害化。 还提供了用于该方法的用于石棉解毒的水溶液。 石棉解毒方法包括:使含石棉的废料与含有至少一种选自碱金属,碱土金属和氨的氟化物和氢氟酸的至少一种氟离子源的水处理溶液接触,以及 进一步含有选自盐酸,硫酸和硝酸中的至少一种无机酸,使得所述水处理溶液的pH为1或更低; 并使所得混合物静置或搅拌,同时加入无机酸,以使水溶液的pH值保持在1以下。 因此,含石棉废料中的石棉是无害的。
