Examples for ppm to sub ppm level analysis of heavy elements

There has been a growing demand globally for the analysis of environmental hazardous substances. In Japan, The Japanese environmental regulation for a trace of zinc in wastewater has been recently revised from 5 mg/l (5 ppm) down to 2 mg/l (2 ppm).

This report introduces an X-ray fluorescence (XRF) analysis for the detection of ppb level of a trace of zinc in wastewater and also hazardous heavy elements in river water using a high sensitivity micro-droplet filter paper, “Ultracarry”, and the newly developed vacuum dryer, “Ultradry”.
