A simple solid phase extraction (SPE) based on sodium dodecyl sulfate grafted chitosan nanocomposite was developed for simultaneous spectrophotometric determination of crystal violet (CV) and malachite green (MG) content ...

Polythiophene (PT) coated magnetic multi-walled carbon nanotubes (MMWCNTs) as a magnetic sorbent was synthesized and characterized by FT-IR, SEM, XRD, and VSM. The sorbent was applied for simultaneous solid-phase microextraction ...

As a promising alternative for the mercury film electrode (MFE), the bismuth film electrode (BiFE) has been widely used in the field of electrochemical analysis. BiFE shows attractive properties and excellent performance ...

The intensive use of thiram and thiophanate methyl fungicides in agriculture leaves residues on crops and contaminates groundwater and surface water bodies through leaching. For the purpose of monitoring pollution arising ...

Lead is known as a toxic metal for human health and used in many industries. For instance, it is frequently used as a material for plumbing systems in drinking water cooler. Another typical materials containing lead is ...

In this study, a dispersive liquid–liquid microextraction method using an extraction solvent lighter than water has been developed for the extraction and preconcentration of cholecalciferol and calcifediol from plasma ...

Poly (threonine) modified carbon paste electrode (PTMCPE) can be used as a responsive and selective electrocatalytic sensor for the estimation of riboflavin (RF) by means of cyclic voltammetry (CV) and differential pulse ...

One new azo Schiff-base derivative: 4-bromo-1,2-bis[2-hydroxy-5-(phenylazo)benzylideneamino]benzene (H2L) was synthesized and characterized by common spectroscopic techniques and elemental analysis. The ability of the new ...

AgNPs-Tragacanth conjugate gel as an eco friendly and low cost membrane was applied for the effective electromembrane extraction (EME) of Tenofovir disproxil fumarate, an important acidic and high polar (log p=1.25) antiviral ...
