Abstract This work reports a simple and sensitive on-line solid-phase extraction system for the pre-concentration determination of trace amount Co(II (ions by flame atomic absorption spectrometry (FAAS). method is based on retention cobalt ions with polyvinyl chloride modified 3-(2-thiazolylazo)-2,6-diaminopyridine in mini-column system. The retained Co(II) were eluted 1.0 mol L −1 HCl, direct ...

ƒ unc X is a distributed function as service (FaaS) platform that enables flexible, scalable, and high performance remote execution. Unlike centralized FaaS systems, decouples the cloud-hosted management functionality from edge-hosted execution functionality. X's endpoint software can be deploy...

Mao-tai lees (ML) is a by-product produced in the process of liquor production and contains high levels crude protein, starch fiber, large yield. Thus, ML has potential to become feedstuffs alternatives livestock production. The present study evaluated nutritional values fermented (FML), including first stage (FML I; microbial fermentation), second (FMTL II; final (FFML; fermentation with prote...

The presence of heavy metals in vegetable oils has negative health effects when consumed by living organisms. As a result, assessing mineral extraction methods is critical for monitoring concentration levels and ensuring oil quality. This study describes new analytical method the determination cadmium (Cd), chromium (Cr), lead (Pb) edible sunflower using emulsion followed flame atomic absorptio...

a novel, magnetic silica sorbent with polyelectrolyte multilayers (pems) on its surface was prepared, and was used for magnetic solid phase extraction (mspe) of trace a+ via flame atomic absorption spectrometry (faas). the experimental parameters for the mspe procedure, such as the ph, type, and concentration of eluent, ultrasonic time and effects of co-existing ions were investigated. the dete...

In this study, we combined Ionic Liquid-based Dispersive Liquid Liquid Micro Extraction (IL-DLLME) with FAAS for determining the palladium in different real samples at the trace level. 1-hexyl-3-methylimidazolium hexafluorophosphate [Hmim][PF6] ionic liquid and 1-(2-pyridylazo) 2-naphthol (PAN), were chosen as the extraction solvent and the chelating agent, respectively. The hydr...

A rapid, simple and cost effective solidified floating organic drop microextraction (SFODME) and flow injection flame atomic absorption spectrometric determination (FI-FAAS) method for copper was developed. In this method, a free microdrop of 1-undecanol containing 1,5-diphenyl carbazide (DPC) as the complexing agent was transferred to the surface of an aqueous sample including Cu(II) ions, whi...
