Photochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

Selective Membrane Electrode for Bromide Ion Based on Aza Pyrilium Ion Derivative as a new Ionophore.

A highly selective electrode for Bromide ion based on aza pyrilium derivative as an excellentionophore is described.The sensor exhibits a good linear response with a slope of ( 60±1 ) mV per decadeover the concentration range of ( 1×10-3 – 9×10-6 M ) , and a detection limit of ( 3×10-6 M ) of Bromideions .The electrode response is independent of pH in the range of(4.0 –9.5).Selectivity coeffici...

Ion-By-Ion Cooling Efficiencies

We present ion-by-ion cooling efficiencies for low-density gas. We use Cloudy (version 10.00) to estimate the cooling efficiencies for each ion of the first 30 elements (H–Zn) individually. We present results for gas temperatures between 104 and 108 K, assuming low densities and optically thin conditions. When nonequilibrium ionization plays a significant role the ionization states deviate from...
