THE INTERACTION OF SILICIC ACID WITH IRON(Ill) A N D U R A N Y L IONS IN DILUTE AQUEOUS SOLUTION

چکیده
An equilibrium constant Q1 --0.57 was obtained in 0.1M NaCIO4 media at 25°C by use of u.v. spectrophotometry. Attempts to reproduce this result in our laboratory, with the aim of extending the technique to other metal ions, have met with considerable difficulty. We will show here that much of the difficulty can be traced to the presence of multimeric silica species, assumed not to be present in the original work. Some data for the interaction of polymeric silica with iron(Ill) is given. Application of the spectrophotometric technique to the study of a silicato-uranyl complex is then presented.

Removal of Strontium Ions by Synthetic Nano Sodalite Zeolite from Aqueous Solution
In this research, the zeolite sodalite, as an inorganic ion exchange material, was chemically produced in the template-free synthesis and evaluated in order to facilitate the sorption of strontium ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The following indicates what the batch experiments included: a sorbent amount of 0.25 g in 100 mL...

We consider the quasilinear Kirchhoff's problem$$ u_{tt}-phi (x)||nabla u(t)||^{2}Delta u+f(u)=0 ,;; x in {mathcal{R}}^{N}, ;; t geq 0,$$with the initial conditions $ u(x,0) = u_0 (x)$ and $u_t(x,0) = u_1 (x)$, in the case where $N geq 3, ; f(u)=|u|^{a}u$ and $(phi (x))^{-1} in L^{N/2}({mathcal{R}}^{N})cap L^{infty}({mathcal{R}}^{N} )$ is a positive function. The purpose of our work is to ...
