This investigation studied the utilization of water hyacinth (Eichhornia crassipes) as biochar
for adsorption of trivalent chromium ion. The prepared biochar has been characterized by …

Abstract Series of resin selection experiments were carried out and the KIP210 strong base
anion exchange resin was confirmed to have the maximum equilibrium adsorption capacity …

Activated carbon was produced from tea-industry wastes (TIWAC) and employed as a low
cost and effective solid phase material for the separation, preconcentration and speciation of …

EFSA received a request from the Hellenic Food Authority for a scientific opinion on
estimation of the risk to human health from the presence of chromium (Cr) in food …

A new simple and sensitive preconcentration, separation and environmentally friendly
method based on carrier element free coprecipitation (CEFC) was developed using 4-(2 …

A novel sorbent material employing magnetic nanoparticles (MNPs) coupled to graphene
oxide (GO) functionalized with 4-aminobenzenesulfonic acid (M@ GO-ABS) has been …

In this paper, a rapid and simple method using magnetic multi-walled carbon nanotubes
