Mass transfer and kinetics of methyl iodide to aqueous drops containing mercury. [Photolysis]
Experiments were performed in a wind tunnel in the presence of artificial light to simulate hydrocarbon interactions with an airborne aqueous drop containing mercury salts. Each drop containing either mercuric sulfate or chloride (concentrations of 10/sup -3/ to 10/sup -9/ M) was suspended for 1 to 10 seconds in a tunnel containing methyl iodide (CH/sub 3/I) (gas concentrations varied 2.3 x 10/sup -7/ M). The mass transfer of the CH/sub 3/I to the drop and subsequent reaction in the drop were studied. The presence of ethyl mercury iodide was identified in the liquid drop. A mass transfer-kinetic model was developed to quantize the process, and the reaction of CH/sub 3/I was found to be pseudo-second order.
