New analytical procedure based on a cellulose bag and ionic exchanger with p-aminobenzoic acid groups for differentiation of labile and inert metal species in aquatic systems
(Springer, 2006-12-01)
A new procedure was developed for the in situ characterization of the lability of metal species in aquatic systems by using a system equipped with a diffusion membrane and cellulose organomodified with p-aminobenzoic acid ...
Advances in metal-assisted non-electrophilic fluoroalkylation reactions of organic compounds
(Elsevier, 2015-02)
Metal-assisted trifluoromethylation and perfluoroalkylation reactions are probably one of the first approaches employed to achieve fluoroalkyl-group substitutions of organic substrates through the use of metals such as ...
Characterization of humic-rich hydrocolloids and their metal species by means of competing ligand and metal exchange - an on-site approach
(Royal Soc Chemistry, 2002-10-01)
An improved on-site characterization of humic-rich hydrocolloids and their metal species in aquatic environments was the goal of the present approach. Both ligand exchange with extreme chelators ( diethylenetetraaminepentaacetic ...

Lability of heavy metal species in aquatic humic substances characterized by ion exchange with cellulose phosphate
(Elsevier B.V., 1997-01-01)
Labile metal species in aquatic humic substances (HSs) were characterized by ion exchange on cellulose phosphate (CellPhos) by applying an optimized batch procedure. The HSs investigated were pre-extracted from humic-rich ...

Approach combining on-line metal exchange and tangential-flow ultrafiltration for in-situ characterization of metal species in humic hydrocolloids
(Springer Heidelberg, 2010-05-01)
This paper deals with the development and optimization of an analytical procedure using ultrafiltration and a flow-injection system, and its application in in-situ experiments to characterize the lability and availability ...

Phytoremediation of Soils Contaminated with Metals: Current Outlook and Prospects of use of Forest Species
(Brazilian Chemical Soc, 2019-01-01)
Phytoremediation is a technique that uses plants to recover contaminated soils. This method has advantages because of its permanent nature, combined with low maintenance costs, protection against wind and water erosion and ...
Effects of metals on activity and community of sulfate-reducing bacterial enrichments and the discovery of a new heavy metal-resistant SRB from Santos Port sediment (São Paulo, Brazil)
(2022-01-01)
Sulfate-reducing bacteria (SRB) can be used to remove metals from wastewater, sewage, and contaminated areas. However, metals can be toxic to this group of bacteria. Sediments from port areas present abundance of SRB and ...
