The mechanism for formation of Cr6+ compounds which were produced by high temperature oxidation reaction of Cr-Ca and Cr(OH)3 systems was investigated. The following conclusions were drawn: (1) When Cr(OH)3-Ca(OH)2 system was burned, Cr6+ compounds were produced by two different mechanisms, which were distinguished by the boundary temperature of 300°C. At temperatures above 300°C, Cr6+ compounds were produced by the mechanism proposed by Nishino et al.; but at temperatures below 300°C, Cr6+ compounds were produced by the following reaction: 4Cr(OH)3+4Ca(OH)3+3O2→4CaCrO4+10H2O (2) CrO3 was prouced by burning of Cr(OH)3 including oxidable anions such as SO42+; and the amount of CrO3 compounds produced was maximum at 250°C. Therefore, it was impossible to prevent the production of Cr6+ compounds in the low temperature burning of real sludge. (3) When Cr-Ca system was burned, the amount of Cr6+ compounds produced became constant at a time at a temperature of 440-600°C; but, at temperatures above 700°C, the surface began to fuse and the reaction proceeded to the interior of particles so that the amount of Cr6+ compounds produced increased with the rise of temperature.

This study investigated synergic effects of phosphoric acid(H3PO4), amino-propyltriethoxysilane(3-APS)and ammonium metavanadate(NH4VO3)in a conversion coating on electro-galvanized steel(EG)to clarify EG corrosion suppression by these substances.Results showed that the ratio of white rust during salt spray testing(SST)was lessened when a coating was formed with 3-APS and H3PO4. The phenomenon was explained: adding 3-APS into H3PO4 causes the decrease of corrosion resistance by suppressing salt water uptake in the coating because the coating itself became compact. Moreover, a coating formed with NH4VO3, 3-APS, and H3PO4 exhibited higher corrosion resistance in SST than a coating with 3-APS and H3PO4. Results show that NH4VO3 changed more into tetravalent or trivalent vanadium by oxidation reaction of zinc when the coating was formed together with 3-APS and H3PO4 on EG. These vanadium compounds in the coating were estimated as dissolved easily in the case in which salt water permeated into coating. The compounds were then deposited at the corroded area to reduce EG corrosion. These findings suggest that NH4VO3, 3-APS, and H3PO4 in the conversion coating contributed both to the high barrier and to self-protective effects of the coating.

The inhibition effects and mechanism of benzotriazole (B.T.A.) on tarnishing and corrosion of silver were studied by means of potentiostatic polarization curves, differential capacity-electrode potential curves, and accelerated testings in H2S and SO2 atmospheres. It was recognized that B.T.A. had little inhibition effects in acidic solutions (pH 2.5), but had great effects in almost neutral solutions; because, B.T.A.-Ag complex was formed on the surface in anodic potential region, and B.T.A. was adsorbed on the surface with lone electron-pairs of N-atoms in cathodic potential region. Silver treated with B.T.A. had an enhanced resistance to tarnishing in H2S atmosphere. It was considered that the prevention would be due to the formation of stable B.T.A.-Ag film on the surface. The galvanic corrosion of silver-plated panels occurred in SO2 atmosphere, leading to the copper base owing to the presence of pores, was much more markedly inhibited by electrolytic treatment than immersion treatment in B.T.A. solution. It was found that the change in the surface coverage (θ) of B.T.A. treated copper conformed to Langmuir's adsorption formula expressed as follows: θ=Km/(1+Km), where K: adsorption constant and m: concentration of B.T.A. Then, the changes of K by immersion treatment and by electrolytic treatment were measured. As the results, a larger value of K was obtained by electrolytic treatment. Therefore, it was considered that the adsorption of B.T.A. on copper through pores became easier by electrolytic treatment.

Wastewater containing tetrafluoroboric acid-hexavalent chromium was decomposed to fluorine (HF) and boron (H3BO3) in acidic conditions using excess aluminum sulfate at normal temperature. In subsequent processing, boron was separated by coagulation-sedimentation using ettringite and calcium hydroxide in highly alkaline conditions. This processing reduced the boron concentration to 10 mg dm-3 or less in the effluent standard. The ettringite used in this experiment was prepared using aluminum sulfate and calcium hydroxide. Alkaline filtered water containing aluminum ion and calcium ion was pH-adjusted to 6.5-7.0 for fluoride removal. This continuous process produced fluorine concentrations of 8 mg dm-3 or less in the effluent standard. Based on these experiments, we devised a practical advanced wastewater treatment system including processing of tetrafluoroboric acid using ettringite. The contents of this paper will contribute to solving treatment problems for metal surface treatment wastewater containing fluorine and boron, also help in the treatment of other industrial wastewater.
