Abstract

The solubilities of methylmercury(II) chloride (MMC), methylmercury(II) bromide (MMB), methylmercury(II) iodide (MMI), ethylmercury(II) chloride (EMC), and ethylmercury(II) bromide (EMB) in water have been determined over the temperature range of 10–55 °C (20–40 °C for MMC and EMC). The temperature dependence of the solubilities expressed as mole fractions x2 was given by the following equations:
& logx_2(MMC)=-1059/T+0.176 (20–40°C)
& logx_2(MMB)=-1094/T-0.263 (10–55°C)
& logx_2(MMI)=-463/T-3.246 (10–25°C)
& logx_2(MMI)=5.498×10^6(1/T)^2-3.711×10^4(1/T)+57.814 (25–55°C)
& logx_2(EMC)=-1048/T-0.612 (20–40°C)
& logx_2(EMB)=-179/T-4.293 (10–25°C)
& logx_2(EMB)=5.389×10^6(1/T)^2-3.603×10^4(1/T)+55.322 (25–55°C)
The thermodynamic parameters for the transfer process from solid to saturated aqueous solution were also determined.
