Abstract

This article deals with the determination of the order of reaction of the ion exchange of uranium(VI)with hydrous titanium oxide in seawater by means of differentiation.We designed flowing concentrated seawater with a variety of Uranium concentrations (C_R),and obtained the "Uranium extract-Time" Curve, obtained the tangent at t=0, found the slope, which is the rate of ion exchange (d C_P/dt)_t-v (for simplification, foot sign t=0 is omitted hereinafter),as shown in figures 1 to 6, Various concentrations of uranium C_R correspond to various values of (d C_P/dt).
