In the last few years, nanomaterials are widely used sorbents for the extraction of heavy
metals in food samples. The nanomaterials have a larger surface area and show high …

Ion imprinting is an extension of molecular imprinting in which target ions are used as
templates to prepare ion-imprinted polymers (IIPs) with specific ion recognition. IIPs have …

This paper presents an overview of the more recent applications of solid-phase extraction
(SPE, from January 2015 to September 2018, which have been recorded in Web of Science) …

Solid phase extraction (SPE) is an analytical procedure developed with the purpose of
separating a target analyte from a complex sample matrix prior to quantitative or qualitative …

A novel hollow-sphere structure of tungsten trioxide and titanium dioxide (WO 3/TiO 2)
heterojunction was prepared by using a combination of hydrothermal and calcination …

This work presents a critical review of multivariate techniques employed for optimization of
methods developed in food analysis. A comparison between the response surface …

Food dye quantity as well as their permitted limit and type, is of particular importance in the
food industry. Hence, it is imperative to develop alternative methods to measure them in food …

An easy and efficient homogeneous adsorption of chitosan for metal ions in a single and
binary metal ion systems was investigated. The chitosan solution was firstly mixed into the …

An ion-imprinted sorbent (Ni-CDMO) derived from diacetylmonoxime (DMO)-chitosan Schiff
base has been prepared by incorporating Ni (II) ion matching sites, which can selectively …

Surface functionalization of two-dimensional (2D) transition metal carbides, nitrides, and
carbonitrides, also known as MXenes, is a powerful approach for modification of their …
