A new approach to an efficient and selective extraction of Cs+ ions from water, sea water enriched with a radioactive solution simulating the effluents Fukushima reactors (137Cs, 29 kBq L−1) was developed by using porous silica- or glass-based nanocomposites containing Prussian blue type nanoparticles, Co2+/[Fe(CN)6]3−, sizes below 10 nm. particular emphasis is given on kinetics cesium sorption fitted classical reaction order model as well diffusion in better understand mechanism. Compared...
Five metal-potassium hexacyanoferrate/chitin composites (based on Cu, Ni, Zn, Co or Fe co-metal) have been prepared and characterized, using SEM-EDX, TEM, X-ray diffraction FT-IR, before being compared for Cs(I) 137Cs(I) sorption. The Zn-ion exchanger was characterized by a much larger crystal size of about 250 nm with few tens other ion-exchangers. ion-exchangers are well distributed in the whole mass composite they fully accessible to Cs(I), as evidenced distribution after metal Uptake...
We present an original approach for preparing silica-based nanocomposites containing Prussian blue-type nanoparticles via click chemistry. Click reaction is used to prepare a triazole-copper complex in single step; this subsequently anchor copper hexacyanoferrate within porous silica matrix (porous glass pearls or SBA-15). This CuAAC "click reaction" was performed using relatively large concentration two reasons: First, the Cu catalyzes triazole ring formation, then acts as chelator,...
Copper hexacyanoferrate nanoparticle functionalised silica monoliths were synthesized following a one-pot procedure to selectively uptake radioactive <sup>137</sup>Cs in water.
The decontamination of wastewater is an important issue for the nuclear industry. removal Sr2+, one most problematic radioelements, requires hierarchical materials suitable fixed-bed processes. This article describes a patented emulsion-templating route synthesis Linde Type A (LTA) zeolite-geopolymer composites with multiscale porosity. By dispersing zeolite particles in emulsion oil-in-water containing precursors geopolymer, LTA zeolite–geopolymer can be obtained after curing and...
