Title:
FILTER CAPABLE OF REMOVING MERCURY IN HIGH PURITY GAS OR AEROSOL
Document Type and Number:
WIPO Patent Application WO/2017/024815
Kind Code:
A1
Abstract:
A filter capable of removing mercury in high purity gas or aerosol comprises a cylindrical outer chamber (2) having an inlet pipe (3) and an outlet pipe (5) respectively at the two ends thereof, and multiple groups of stepped liners (1) and tapered outer casings (4) that are cooperatively mounted within the outer chamber (2). One stepped liner (1) is mounted between two adjacent tapered outer casings (4). Both step faces of the stepped liners (1) and step holes of the tapered outer casings (4) have gold coatings of 2-10 μm. A void channel (6) is formed between the step faces of the stepped liners (1) and the step holes of the tapered outer casings (4), and the inlet pipe (3) and the outlet pipe (5) are connected by the void channel (6). Gold amalgam is formed by means of absorption of mercury by the gold coating to realize the filtration of mercury, making possible analysis of ultralow quantities of lead isotope in a mineral, which is otherwise impossible in the current field of microanalysis. The invention is of great significance in the research of zircon dating and analysis of the composition of monomineralic lead isotope using the current laser ablation quadrupole plasma mass spectrometry and multi-collector plasma mass spectrometry techniques.
