The XRF analysis results were verified with other consecrated method such AAS and ICP-MS using standardized methodologies, including pretreatment of samples. Good correlation of results between methods was achieved (usually 0.93-0.98). Minimum sample preparation (drying, sieving and prolene cup preparation) is needed, and up to 4 samples can be analyzed per hour. Usual limit of detection for analyzed elements was between 3 and 30 mg/Kg dw, with higher limits for light elements as Mg (384 mg/Kg dw) Al(162 mg/Kg dw). XRF analysis method was successfully used for analysis of some precipitates obtained from mine waters using various precipitation methods. Mine water was sourced from some closed Romanian mines.Energy Dispersive X-ray FluorescenceMine water treatmentHeavy metalsSymposium Proceedings
