Publikováno v: Journal of Hazardous Materials. 336:93-100

Summarization: This article describes the detoxification of pure chrysotile (Chr) asbestos by following an acid leaching treatment with oxalic acid dihydrate (Oxac) (H2C2O4·2H2O). Oxac was chosen due to its low environmental impact (or toxicity) and
