The present paper is aimed at introducing its authors' examination of the influence of dissolved oxygen level, the wavelength of incident light and the concentration of Fe on the photo-production of DIC mineralization of dissolved organic carbon by using a Suntest CPS solar simulator.

The photochemical mineralization of dissolved organic carbon to dissolved inorganic carbon(DIC) is a key process in carbon cycling.

However,growth inhibition of submersed macrophyte by phyto- plankton may be also due to other important factors including alleloph and DIC competition of phytoplanktion.

Influence of land use change on dissolved inorganic carbon and stable isotopic compositions of karst groundwater

Distribution characteristics of dissolved inorganic carbon in southern Yellow Sea in autumn

Dissolved inorganic carbon (DIC) account for more than 95% of total carbon in seawater, so it is necessary to make reliable and precise measurements of DIC to study marine carbon cycling.

This paper reports the production technical arts and principles of chemical agents for 12-tungsten phosphoric(H3PW12O40),12-molybdophpsphoric acids(H3PMo12O40) and solid superacid by the separation of all kinds of elements of Ti,E,Mo,Ni, from the disused Ti(C,N) based ceramics which are applied the inorganic acid solution roasted, soaked crystallzation,precipitated means.
