Estimation of Activities in the Aqueous Solution Systems of HCl–NaCl and HCl–NiCl2 Using the Pitzer Method

Autor: Yoshihisa Hamada, Mikiya Tanaka, Takeo Tamagawa

Publikováno v: Materials Transactions, JIM. 33:380-390

Parameterizations based on the literature activity data have been carried out for the activities of water and the solutes in the aqueous solution systems of HCl-NaCl and HCl-NiCl 2 at 298 K in terms of the Pitzer theory without explicitly considering

A Wet Purification Process for Diatomaceous Earth by Precipitation Method Using Nonaqueous Solvent

Autor: Makoto Takemori, Yoshihisa Hamada, Atsumu Tsunashima

Publikováno v: Shigen-to-Sozai. 107:821-826

A wet silica purification method by precipitation in nonaqueous solvent is studied. This method can be applied in the treatment of resources containing alkali soluble silica. The process consists of three steps. At the first step, silica resource is
