Using XRD methods for the determination of asbetos which affect people's health in Vietnam environment

ABSTRACT

XRD (X Ray powder Diffraction) is an effective analysis method for crystallized materials. This method can identify and reflexes characteristics of asbestos in solid materials clearly based on 3 highest peaks of specific diffraction spectrum from asbestos containing samples. However, asbestos concentration lower than 1% may cause certain biases in analysis. Our study focused on the XRD method for qualitative determination of asbestos in solid material samples in Vietnam environment
