Hydrolyzing metal salts as coagulants*
Aluminium and ferric salts are widely used as coagulants in water and wastewater treatment. They are effective in removing a broad range of impurities from water, including colloidal particles and dissolved organic substances. Their mode of action is broadly understood in terms of essentially two mechanisms: charge neutralization of negatively charged colloids by cationic hydrolysis products an...
متن کاملTransition Metal Salts
Even so, extensive research has been carried out on potential eco-toxic effects of particulate and extensively degraded oxo-biodegradable plastics when mixed with soil. Tests included seed germination and plant growth rates, compared with the same soil without degraded plastics [3,4], the effects on macro-organisms (worms, daphnia, etc.) in the soil [4] and on the accumulation of transition met...
متن کاملMetal Complexes as ligand : Binuclear Ni(II) and Cu(II) metal chelates of p-Methylisonitrosoacetophenone with Alkaline earth metal salts
A number of new binuclear complexes have been synthesised by interaction of stable Ni(II) and Cu(II) metal chelates of p-Methylisonitroacetosophenone with Alkaline earth metal salts having general formula[Ma(p-MeINAP)2MbL2 or MbX2]where Ma=Ni(II) or Cu(II),p-MeINAP = deprotonated pMethyiIsonitrosoacetophenone, Mb= Ca ++ or Mg ++ ,L = deprotonated ortho amino benzoic acid and 8hydroxyquinoline X...
متن کاملAdvances in Oral Coagulants
This article reviews current and future treatment practices concerning oral anticoagulants. In the second decade of the 21st millennium clinicians can finally treat thrombotic disease with long-awaited new oral anticoagulant medications. In addition, improvements have been made in managing warfarin, the traditional but far from obsolete medication. The first part of this review will cover curre...
متن کاملHaloaurate and halopalladate imidazolium salts: structures, properties, and use as precursors for catalytic metal nanoparticles.
The synthesis and characterisation of a series of new gold- and palladium-containing symmetrical imidazolium salts are described which display significant cation-dependent effects determined by the structure of the alkyl chains of the imidazolium motifs. Whereas direct reduction of the Pd salts can produce stable nanoparticles (NPs) coated by imidazolium salts, the addition of strong base to th...
