Heavy metal is released from many industries into water. Before the industrial wastewater is
discharged, the contamination level should be reduced to meet the recommended level as …

This review presents the most recent applications of solid phase extraction for the
separation, preconcentration and speciation of metals, metalloids, and organometals. The …

We report the synthesis and activation of colloidal carbon nanospheres (CNS) for adsorption
of Ag (I) ions from aqueous solutions. CNS (400–500nm in diameter) was synthesized via …

In this paper, green and facile synthesis of sulfur‐and nitrogen‐codoped carbon
nanospheres (CNs) was prepared from the extract of Hibiscus sabdariffa L by a direct …

We have developed a fast method for sensitive extraction and determination of the metal
ions silver (I), gold (III), copper (II) and palladium (II). Fe 3 O 4 magnetic nanoparticles were …

A novel separation–preconcentration procedure based on ionic liquid dispersive liquid–
liquid microextraction of traces lead as pyrrolidinedithiocarbamate chelate has been …

Chloromethyl styrene-divinylbenzene (PS–Cl) resin was usually chemically modified for the
adsorption of heavy metal ions in wastewater. However, this work will introduce a new …

In this study we investigated the efficiency of a wide panel of 24 solid sorbents comprising
layered structures (hydrotalcites and zirconium phosphates), magnesium oxide and …

This study presents a simple and effective method of preparation of N-(2-sulfoethyl) chitosan
(NSE-chitosan) that allows obtaining a product with a degree of modification up to 1.0. The …

To extract polyaromatic hydrocarbons (PAHs) from water samples using the Solid Phase
Extraction (SPE) method. Based on hemimicelle/admicelle formation on the oxide surface …
