The effect of pH on the uptake of zinc and cadmium in marine phytoplankton: Possible role of weak complexes
zinc cadmium weak complexes
2014/4/4
In natural samples from the New Jersey coast and the Gulf of Alaska, zinc (Zn) and cadmium (Cd) uptake
rates by phytoplankton decreased on average about 30% as pH was decreased from 8.5 to 7.9 or 7.7...
Uptake properties of Eu(III) on Na-attapulgite as a function of pH, ionic strength and temperature
Eu(III) Sorption Na-attapulgite pH Ionic strength Thermodynamic data
2011/11/10
Herein, the sorption properties of Eu(III) on Na-attapulgite were performed by using batch sorption experiments under different experimental conditions, such as contact time, pH, ionic strength, humic...
Mycotoxins are toxic compounds produced by many species of fungi after infesting grain and other food crops. These toxins can be carcinogenic,mutagenic, teratogenic, oestrogenic,neurotoxic, or immunot...
Use of water uptake and capillary suction time measures for evaluation of the anti-diarrhoeic properties of fibrous clays
Palygorskite Sepiolite Anti-diarrhoeic MBA Water uptake CST
2011/11/8
This study explores the use of water sorptionrretention measures as alternative methodologies to the official methylene blue adsorption test for the evaluation of the anti-diarrhoeic properties of som...
Bioaccumulation of metals by lichens:Uptake of aqueous uranium by Peltigera membranacea as a function of time and pH
Bioaccumulation aqueous uranium by Peltigera membranacea pH
2012/4/1
Uranium sorption experiments were carried out at ;258 C using natural samples of the lichen Peltigera membranacea. Thalli were incubated in solutions containing 100 ppm U for up to 24 h at pH values f...
An Aluminum Pillared Montmorillonite with Fast Uptake of Strontium and Cesium from Aqueous Solutions
Cation Exchange Capacity Delamination Pillared Clay Radiocesium Radiostrontium Uptake
2011/12/22
Abstract: The uptake of Sr and Cs by 2 types of aluminum pillared layered clays (Al-PILC), a reference sample (AZA) and a specially tailored sample (FRAZA), were investigated. The AZA sample was prepa...
Uptake of Lanthanides by Vermiculite
Hydration energy Hydrolysis Infrared spectroscopy Ion exchange Lanthanide ions Vermiculite X-ray powder diffraction
2011/11/30
Abstract: The uptake of Ce3+, Nd3+, Gd3+, Er3+, and Lu3+ on vermiculite was studied using cation-exchange measurements, infrared spectroscopy (IR), and X-ray powder diffraction (XRD). The reaction was...
Exchange and Selective Surface Uptake of Cations by Layered Silicates Using X-ray Photoelectron Spectroscopy (XPS)
Beidellite Cation Exchange Surface Exchange X-ray Photoelectron Spectroscopy
2012/2/10
The cation-exchange capacities (CEC) of a previously well-characterized beidellite have been estimated nondestructively from X-ray photoelectron spectroscopy (XPS) data following exchange by various c...
