alkali ion
3.In a dense alkali potassium vapor excited by argon-ion laser 476.5nm line,the emission spectra of K2 diffuse band have been observed.
6.Alkali-rich porphyry is relatively enriched in large-ion lithophile elements(K,Rb and Ba)and de - pleted in high-field strength elements(Nb,Ta,Ti and P)with a wider range of Nb/Y ratios and shows strong REE fractionation but no pronounced negative Eu anomaly — all these suggest that the magma source region un - derwent metasomatism and concentration of ancient subducted oceanic slab fluids and was injected by small streams of melts from the asthenosphere.
7.The interaction of thermal alkali atoms on hot tungsten and platinum filaments has been studied experimentally. The positive ion current has been measured as a function of the surface temperature. Electron exchange between the adatom and metal surface and the change of work function of the adsorbed metal surface have been discussed.
9.5. L-lactic acid separation with ion exchange resin was studied, and the most suitable ion exchange resin D185 was selected, and its exchange capacity and the desorption ratio was 75g/L and 87% respectively. Glucose and amino nitrogen were not absorbed by the resin and the most suitable reproductive alkali was NH3 H2O.
