extraction-fluorimetric determination of trace amounts of mercury by 1,10-diaza-18-crown-6 and rose bengal
نویسندگان
چکیده
a simple and sensitive extraction-fluorimetric method for the determination of mercury is reported. the method is based on the quantitative extractionof a ternary crown-mercury-rose bengal complex into chloroform at ph 10 followed by fluorimetric measurements at 580 nm. a linear working range from 0.05 to 2.00 mg/ml is obtained. the relative standard deviation for 1.0 mg/ml mercury is 3.5%. the procedure was successfully applied to the determination of mercury in fish and mercurochrome.
