In aqueous systems, heavy metal ions, when present in excess than permissible limits, are
dangerous for human beings and aquatic life. Heavy metals cannot be degraded. Rather …

The current rapid development of green analytical chemistry (GAC) requires clear, concise
guidelines in the form of GAC principles that will be helpful in greening laboratory practices …

In the present study, highly porous composite material (PCM) was fabricated by novel ligand
immobilization onto the silica monolith for Pb (II) ion detection and adsorption from …

A novel hierarchical composite adsorbent was developed for sensitive and selective lead
(Pb (II)) ions detection and removal from wastewater as well as biological samples optically …

It is important to develop new materials for analytical sample preparation for the separation,

Cloud-point extraction (CPE), an easy, safe, environmentally friendly, rapid and inexpensive
methodology for preconcentration and separation of trace metals from aqueous solutions …

Graphene, a novel class of carbon nanostructures, has great promise for use as sorbent
materials because of its ultrahigh specific surface area. A new method using a column …

Interference of organic compounds in the matrix of heavy metal solution could suppress their
pre-concentration and detection processes. Therefore, this work aimed to develop simple …
