متن کاملConstruction of a Carbon Paste Electrode Based on Novel Thiolated Ligand Capped Gold Nanoparticles for Determination of Trace Amounts of Mercury(II)
In the present study, a simple electrochemical sensor for trace determination of Hg(II) ions in aqueous solutions was introduced. The proposed sensor was designed by incorporation of the 4-methyl-piperidine-carbodithioate capped gold nanoparticles (GNPs) into the carbon paste electrode (CPE), which provides a remarkably improved sensitivity for stripping voltammetric determination of Hg(II). Di...
متن کاملQuantifying the coverage density of poly(ethylene glycol) chains on the surface of gold nanostructures.
The coverage density of poly(ethylene glycol) (PEG) is a key parameter in determining the efficiency of PEGylation, a process pivotal to in vivo delivery and targeting of nanomaterials. Here we report four complementary methods for quantifying the coverage density of PEG chains on various types of Au nanostructures by using a model system based on HS-PEG-NH(2) with different molecular weights. ...
متن کاملThe Effect of Kinetics Parameters on Gold Extraction by Lewis Cell: Comparison between Synthetic and Leach Solution
Modern hydrometallurgical techniques have been adopted to produce high-purity gold. Many extractants were used for the extraction of gold from various synthetic solutions from which DiButyl Carbitol (DBC) had a unique superiority. Kinetics of process was studied in this paper and the influence of several parameters such as stirring speed, agitation time, impeller type, interfacial area, [Au...
