Objective To determine the free SiO2 in micro-amounts (0.1～5 mg) of respirable dust. Methods A method for X-ray diffraction was carried out. Results The relative errors were below 10%. The accuracy of the proposed method was able to meet the requirement of routine micro-amounts. Conclusion X-ray diffraction might be an accurate, convenient and speed-up method to measure free SiO2 in airborne sample collected by filter membrane.
