A modified introduction device and a preconcentration method were developed to enhance the sensitivity of Hg isotopic analysis method.
An isotope binary mixing model was applied for high precision measurement of mercury ratios in samples with low concentrations by multicollector inductively coupled plasma mass spectrometry (MC-ICPMS). Standard addition used to evaluate the and accuracy composition calculations resulting from model. A high, steady 202Hg signal approximately 2.13 V achieved, concentration reaching 3 ng/mL. The isotopic three standards (NIST SRM 1646a; NIST 1575a; BCR 482) natural were precisely determined....
This study assesses the impact of simulated sea level rise (SLR) on mercury distribution and migration in an urban mangrove wetland northern coast Maluan Bay, Xiamen City, Fujian Province, China. Two adjacent Kandelia obovata plots with elevations representing current a 40-cm SLR were examined. Total (THg), methylmercury (MeHg), isotopes sediments from different analyzed to reveal geochemical behavior under 100-year scenario. THg MeHg mirrored patterns biogenic elements (carbon, nitrogen,...
An automatic flow system of rapid on-line sampling, digestion, and pre-concentration for in-field determination total mercury in seawater has been developed. In this system, both UV radiator bromine monochloride (1%, v/v) were used to make the sample digestion reliable. And, active gold columns effective preconcentration mercury. Double loops connected an 8-way valve adopted quantitate volume samples reductant, respectively. With hyphenation cold vapor atomic fluorescence spectrometry...
