A novel method for synthesizing large scorodite (FeAsO4.2H2O) particles was recently developed for the fixation of arsenic. This method involves the coprecipitation of scorodite particles from an Fe(II) and As(V) aqueous solution at approximately 95 C by oxygen injection. In order to understand the process of coprecipitation of scorodite particles by this method, X-ray diffractometry (XRD), sca...

Magnetic nanoparticle (MNP)-based magnetic resonance imaging (MRI) contrast agents (CAs) have been the subject of extensive research over recent decades. The particle size of MNPs varies widely and is known to influence their physicochemical and pharmacokinetic properties. There are two commonly used methods for synthesizing MNPs, organometallic and aqueous solution coprecipitation. The former ...

This research discusses the development of magnetic materials as an effort to produce renewable catalysts in overcoming energy crisis. The purpose this study was synthesize and characterize MgO/CoFe2O4 nanoparticles using coprecipitation method. synergy between substances that are catalysts, namely MgO CoFe2O4 expected a superior catalyst for biodiesel production. stages were by continued with ...
