Separation of Zirconium and Hafnium by Extraction with 2-octanol.

Zirconium and hafnium are shown to be separable using 2-octanol (C8H18O) as an extractant.Zirconium basic carbonate was dissolved using hydrochloric acids at concentrations ranging from 5 % to 20 %.Potassium fluoride was found to be crucial to the process.Its effect was investigated in the concentration range of 1 M to 3 M.The optimum conditions ob

Molecular Mechanisms on the Selectivity Enhancement of Ascorbic Acid, Dopamine, and Uric Acid by Serine Oligomers Decoration on Graphene Oxide: A Molecular Dynamics Study

The selectivity in the simultaneous detection of ascorbic acid (AA), dopamine (DA), and uric acid (UA) has been an open problem in the biosensing field.Many surface modification methods were carried out for glassy carbon electrodes (GCE), including the use of graphene oxide and amino acids as a selective layer.In this work, molecular dynamics (MD)
