Removing rubidium using potassium cobalt hexacyanoferrate in the membrane adsorption hybrid system

Size dependence of the photoinduced magnetism and long-range ordering in Prussian blue analog nanoparticles of rubidium cobalt hexacyanoferrate

Nanoparticles of rubidium cobalt hexacyanoferrate (RbjCok[Fe(CN)6]l · nH2O) were synthesized using different concentrations of polyvinylpyrrolidone (PVP) to produce four different batches of particles with characteristic diameters ranging from 3 to 13 nm. Upon illumination with white light at 5 K, the magnetization of these particles increases. The long-range ferrimagnetic ordering temperatures...

Coexistence of ferroelectricity and ferromagnetism in a rubidium manganese hexacyanoferrate.

Investigation of Membrane De-clogging Techniques in the Submerged Membrane Filtration Adsorption Hybrid System (SMFAHS)

Membrane clogging is a major obstacle to the successful operation of the membrane separation process. A submerged hollow fibre membrane with powdered activated carbon (PAC) adsorption (adsorption-membrane hybrid system) was used for the removal of organics from a synthetic wastewater representative of biologically treated sewage e.fJluent. PAC usage successfully adsorbs the majority of the orga...

Electrocatalytic oxidation of hydroxylamine on glassy carbon electrodes modified by hybrid copper-cobalt hexacyanoferrate films.

An electrochemical sensor for amperometric detection of hydroxylamine was developed by electrodeposition of hybrid copper-cobalt hexacyanoferrate films on a glassy carbon electrode. The modified electrode could reduce the overpotential of the hydroxylamine oxidation by about 400 mV. This sensor exhibited a linear relationship between the response current and the hydroxylamine concentration in t...

A comparison of the distribution of potassium and exchangeable rubidium in the organs of the dog, using rubidium.

From determinations of radioactivity and potassium content at intervals after the injection of Rb, it was inferred that most organs of the dog contained exchangeable rubidium in a concentration paralleling but exceeding that of potassium, as compared with their relative concentrations in the plasma. A "lag phenomenon" resulting in higher rubidium specific activity in the myocardium than plasma ...
