The adsorption and reaction of a titanate coupling reagent on the surfaces of different nanoparticles in supercritical CO2.

The adsorption and reaction in supercritical CO2 of the titanate coupling reagent NDZ-201 on the surfaces of seven metal oxide particles, SiO2, Al2O3, ZrO2, TiO2 (anatase), TiO2 (rutile), Fe2O3, and Fe3O4, was investigated. FTIR and TG analysis indicated that the adsorption and reaction were different on different particle surfaces. On SiO2 and Al2O3 particles, there was a chemical reaction of ...

Adsorption on apatitic calcium phosphates for drug delivery: interaction with bisphosphonate molecules.

Bisphosphonates (BPs) are well established as an important class of drugs for the treatment and prevention of several bone disorders including osteoporosis. This work investigated the interaction of two bisphosphonates, risedronate and tiludronate, with several apatitic supports, a well-crystallised hydroxyapatite (HA) and nanocrystalline apatites with varying maturation times, chemical composi...

Surface modification of hollow magnetic Fe3O4@NH2-MIL-101(Fe) derived from metal-organic frameworks for enhanced selective removal of phosphates from aqueous solution

Hollow magnetic Fe3O4@NH2-MIL-101(Fe) derived from metal-organic frameworks are fabricated through a general facile strategy. The synthetic parameters are regulated to control the shape of the as-prepared samples. The concentration of phosphates decreased sharply from the initial 0.60 to 0.045 mg.L(-1) with the exposure time in 50 minutes. The correlation between the most significant parameters...

EFFECT OF KC1 AND CaC12 AS BACKGROUND ELECTROLYTES ON THE COMPETITIVE ADSORPTION OF GLYPHOSATE AND PHOSPHATE ON GOETHITE

-Competitive adsorption between glyphosate and phosphate on goethite was evaluated. The influence of background electrolyte on the adsorption of glyphosate and phosphate was also investigated by using 0.01 M KC1, 0.1 M KC1 and 0.01 M CaCI 2 as background electrolytes. Experiments showed that phosphate displaced adsorbed glyphosate from goethite, whereas glyphosate did not displace phosphate. Re...

Contribution of adsorption of metals using calcium phosphates in the presence of support polyethylene glycol

The extraction of metals from supports based on calcium phosphate was investigated; we conducted experiments with metal solutions at various concentrations, and using two carriers’ calcium phosphate hydroxyapatite and hydroxyapatite in the presence of polyethylene glycol polymer. The results show a metal retention of selectivity with excellent yields. The kinetic study shows that the extraction...
