To assess the effect of the mould filling modes on the content of oxide films in castings, special criterion is proposed that provides prediction in the contamination of chill castings mаde of aluminum alloys by using modern computing tools to simulate the moulds casting process on computer. It is noted that decrease in the value of the contamination criterion by using alloys with low content of Mg or without this component reduces the possibility of controlling the distribution of oxides in the casting, other elements of the casting mould and using the concentration of oxides, for example, in washers to control the mechanical properties of cast products. This is due to increase in the duration of oxidation processes in gas-tight mould with such change in the composition of the casting material.

A laboratory-scale electrolytic cell with a Ti/RuO2-Pt anode and a Ti cathode was developed to treat high concentration cyanide-contained wastewater. The effects of the different electrode distances, concentration of chlorine anion and current densities, on the CN- removal were investigated. The results shown the too short and long electrode distance resulted in high energy consumption and low current, the appropriate electrode distance was essential. The CN- removal was very significant at the electrode distance was 9 cm, and the removal efficiency reached 99.2%. The removal CN- electrochemical oxidation was mainly attributed the success to in direct oxidation effect of chlorine /hypo-chlorite produced during the electrochemical reaction process. The CN- removal efficiency increased with increasing the concentration of chloride ion and operating current density. The optimum experimental condition was set at the electrode distance of 9 cm, NaCl dosage of 0.5 g/L, the current density of 10 mA/cm2, and pH of 12. At the optimum experimental condition, the CN- concentration in the solution decreased from 150.33 mg/L to 1.20 mg/L, and the CN- removal efficiency reached 99.2%.
