Preparation of Fe3O4Spherical Nanoporous Particles Facilitated by Polyethylene Glycol 4000
Much interest has been attracted to the magnetic materials with porous structure because of their unique properties and potential applications. In this report, Fe3O4nanoporous particles assembled from small Fe3O4nanoparticles have been prepared by thermal decomposition of iron acetylacetonate in the presence of polyethylene glycol 4000. The size of the spherical nanoporous particles is 100-200 ...
متن کاملImmediate allergic reactions by polyethylene glycol 4000: two cases.
The evacuant solution (ES) is a drug that has been used to clean the colon. The most common described side effects when using this drug are abdominal symptoms; skin rash is rare. We report on two patients who presented urticaria and angioedem after the intake of an evacuant solution to make a rectoscopy. We performed allergy studies: skin prick tests with common inhalants, pure ES and the compo...
متن کاملRemoval of Mercury (II) from Wastewater by Magnetic Solid Phase Extraction with Polyethylene Glycol (PEG)-Coated Fe3O4 Nanoparticles
The presented study investigates application of polyethylene glycol (PEG)-coated Fe3O4 nanoparticles as an magnetic nanoadsorbent for magnetic solid-phase extraction (SPE) and the selective removal of toxic heavy metals such as mercury (II) from aqueous solutions and their determination using graphite furnace atomic absorption spectrometry (GF-AAS)...
متن کاملPolyethylene Glycol 3350 With Electrolytes Versus Polyethylene Glycol 4000 for Constipation: A Randomized, Controlled Trial
OBJECTIVE The long-term efficacy and safety of polyethylene glycol (PEG) in constipated children are unknown, and a head-to-head comparison of the different PEG formulations is lacking. We aimed to investigate noninferiority of PEG3350 with electrolytes (PEG3350 + E) compared to PEG4000 without electrolytes (PEG4000). METHODS In this double-blind trial, children aged 0.5 to 16 years with cons...
متن کاملPolyethylene glycol 4000 for treatment of functional constipation in children.
OBJECTIVES The aim of the study was to evaluate the effectiveness and safety of 2 different polyethylene glycol (PEG) doses for the maintenance treatment of functional constipation in children. METHODS Children with functional constipation according to the Rome III criteria were randomly assigned to receive PEG 4000 at a dose of either 0.7 g/kg (high-dose group; n = 45) or 0.3 g/kg (low-dose ...
