ABSTRACT:
Trialkyl arsines are removed from fluids, in particular gases, by contacting with a solid sorbent material containing at least one gold component (preferably AuCl and/or AuCl.sub.3 and/or NH.sub.4 AuCl.sub.4) and a support material (preferably alumina and/or silica). This process can be used for colorimetrically detecting the presence of arsines in gases.
