Determination of As, Hg and Pb in herbs using slurry sampling flow injection chemical vapor generation inductively coupled plasma mass spectrometry

Flexible liquid crystal polymer-based electrochemical sensor for in-situ detection of zinc(II) in seawater

“…Analytical methods, such as atomic absorption spectrometry (AAS) [3,4], inductively coupled plasma atomic emission spectrometry (ICP-AES) [5,6], and inductively coupled plasma mass spectrometry (ICP-MS) [7,8], are usually adopted to determine the concentration of target metal ions. Although these approaches are capable of quantifying the water quality, their complicated operation, high instrumentation cost, and bulky size limit the application for on-site/in-situ measurement.…”

Microextraction based on solidified floating organic drop coupled with ETAAS for the determination of lead in herbs

“…Consequently, traceable and reliable measurement of Pb is essential for the safety and risk assessment for the wide use of traditional and medicinal herbs. Currently, there are some variety methods related to modern instrumentation that have been widely used for heavy metal determination; these include ICP (MS and AES) (Zhao et al 2012;Sorbo et al 2014;Deng et al 2015;Tai et al 2016) and AAS (Demirtaş et al 2015;Batista et al 2016;Zhong et al 2016). However, trace determination of Pb in herb samples is relatively inconvenient because of the matrix effect and low concentration of Pb.…”

“…Finally, the solution is directly determined the analyte concentration. From the literature, there are only few reports related to separation/pre-concentration of Pb in herb samples (Solidum 2014;Tai et al 2016, Lam et al 2010Yavuz et al 2016). Therefore, SFODME technique combination with ETAAS for the Pb determination in herb samples was conducted in this work.…”

Biosorption of Zn2+, Ni2+and Co2+from water samples onto Yarrowia lipolytica ISF7 using a response surface methodology, and analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES)

“…Inductively coupled plasma mass spectrometry (ICP-MS), 44 inductively coupled plasma optical emission spectrometry (ICP-OES), [45][46][47] ame atomic absorption (FAAS), 48 electrothermal atomic absorption spectrometry (ETAAS), 49 and molecular spectrophotometry and other atomic and molecular conventional instrumental techniques have been applied to quantify metals in many samples. Among the available analytical techniques to quantify the elements present in water samples, inductively coupled plasma optical emission spectrometry (ICP-OES) is a multi-element analysis technique that can lead to the achievement of relatively low detection limits and has a practical linear range that makes possible simultaneous and precise determinations in short times over wide concentration ranges.…”
