Background Complexing agents are widely used in various industrial processes and household products throughout the world. Amongst the well-known complexing agents, not only EDTA but also DTPA and NTA are widely used. Possible legislative restrictions of the use of biologically recalcitrant complexing agents brings about studies of novel and alternative products and at the same time more sophist...

liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

Using cloud point extraction technology and the principle of absorbance addition in multi-component system, mixed metal ions Cr (III) Co (II) industrial wastewater were enriched determined at pH 5.0 50℃, using ammonium pyrrolidine dithiocarbamate (APDC) as complexing agent Triton X-114 extractant. The results indicate that contents can be calculated a simultaneous equation system. detection lim...

The work reports the synthesis and characterization of ternary nanoalloy catalysts silver, bismuth, rhenium from alkaline solutions containing L–cysteine as a complexing agent sodium borohydride reducing agent. UV–Vis spectra dynamic light scattering (DLS) analyses obtained colloids were performed. Additionally, high-resolution transmission electron microscope (HR–TEM) analysis assisted former ...
