Abstract
Langmuir-Blodgett (LB) films of mercury(II) arachidate (HgAr) and mercury(II) behenate (HgBe) were deposited on hydrophobed quartz and mica using airwater monolayers of the respective fatty acids spread on subphases containing Hg(OOCCH 3) 2. The reactions of HgAr and HgBe films with H 2S were investigated using ultraviolet-visible-near infrared spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy (AFM), and quartz crystal microbalance techniques. It was concluded that HgS forms quantitatively in the LB films. Additional HgS can be introduced into the film after gassing by immersion of the films in a Hg 2+ solution and regassing with H 2S. Absorbance data do not provide information as to the nature and size of the HgS aggregates in the film. AFM measurements, however, indicate that individual particles are formed in the size range 2–10 nm. Agglomerates of individual particles were also observed.
