Nanoparticles of Fe(3)O(4) were synthesized by hydrolysis in an aqueous solution containing ferrous and ferric salts at various ratios with 1,6-hexanediamine as a base. It was found that the ferrous to ferric ratio influences the reaction mechanism for the formation of Fe(3)O(4). When the ratio of ferrous to ferric ions was increased, the formation of large hydroxide particles as a precursor of...
Ball milling and ultra-sonication size reduction procedures were applied to granular ferric hydroxide (GFH) obtain two micro-sized adsorbents. These adsorbents GFH investigated improve the removal of phosphates from water. The procedures, using method, allowed a 0.5–2 mm 0.1–2 µm total disaggregation structure. Using an method yielded final 1.9–50.3 with partial disaggregation. Langmuir model c...
Ferric hydroxide and ferric hydroxysulfate precipitation by bacteria in an acid mine drainage lagoon
Macroporous chitosan spheres encapsulating superparamagnetic iron oxide nanoparticles were synthesized by a facile and effective one-step fabrication process. Ferro-gels containing ferrous cations, ferric cations and chitosan were dropped into a sodium hydroxide solution through a syringe pump. In addition, a sodium hydroxide solution was employed for both gelation (chitosan) and co-precipitati...
