چکیده
Environmental remediation of hazardous metals like Cd(II), and Co(II) ions is very necessary due to their toxicity at trace accumulation levels in the biosystem. In this study, sorption Co(II), Cd(II) from aqueous solutions onto titano-silicate (TiSi) ion exchange material in-situ dopping composites cobalt (Co-TiSi) cadmium (Cd-TiSi) was achieved. TiSi were obtained by precipitation technique characterized using different analytical tools such as FT-IR, XRD, TGA&DTA, XRF. Results study showed that capacity for revealed Co-TiSi Cd-TiSi a higher than those 1.81, 1.41 times value, respectively. The distribution coefficients function HNO3 have high separation factors concentrations. Langmuir isotherm model most representative discussing process with maximum 16.02, 10.96 mg/g ions, suitable column recovery studied cations. investigation proved exchanger uptake liquid could be considered potential refining effluent polluted these ions.

The unusual electrical, optical, magnetic, and chemical properties of metal colloids (better known in nowadays as metal nanoparticles, MNPs) have attracted increasing interest of scientists and technologists during the last decade. In fact, although Nanoscience and Nanotechnology are quite recent disciplines, there have already been a high number of publications that discuss these topics. [1-11...
متن کاملMetal-organic framework materials as nano photocatalyst
Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...
