摘要

A solvent extraction procedure for the quantitative extraction of trace levels of mehylgermanium species as their chloride complex has been developed has the extract was determined by an on-column capillary gas chromatography with a lab-modified flame photometric detector (FPD) using quartz surface-induced germanium emission after pentylation with Grignard reaction. The extracted percentages for TMGe, DMGe and MMGe in a 100ml 9mol/L HCI aqueous solution by a single extraction with 1 ml hexane are 8606/100, 87.4/100and 96.2/100, respectively.
