methyl mercury
5.Parameters of domestic GC7890 capillary gas-chromatography, affecting the determination of methyl-mercury, including the injection volume,the retention time, the flowrate of carrier gas and supporting gas,and the temperature of input, column, and ECD, were discussed and optimized: input temperature—200℃, columntemperature—160℃, ECDtemperature—200℃, flowrate of carrier gas—60mL/min, supporting gas—30mL/min, injection volume—2μL.
6.As a result,It was foundthat average value of methylmercury in fisher hairs was 2.50 PPm,the contents of daily intake of methylmercury was 69.09μg,the contents of excretion of methyl-mercury in urine was the highest,it wag 13.62μg/24hr,methylmercury in urine increased 42.41 times,and the increased figure was the highest among all sorts of ways of excretion.
9.THE DETERMINATION OF STABILITY CONSTANTS OF TERNARY MIXED LIGAND COMPLEXES OF MERCURY (II) -METHYL THYMOL BLUE-X (SCN, Br, I)
10.A Kinetic Spectrophotometric procedure for the determination of trace mercury was proposed based on the Hg~(2+) which can inhibit the catalysis of I~- in the descolorization of IO~-_4 and methyl orange reaction in buffer medium of C_2H_5KO_4-NaOH(pH=4.5) and cetytrimethylaminonium bromide (CTMAB) solution.
