This paper summarizes the research progress of anode bubble behavior in aluminum electrolysis from three aspects: physical model,laboratory scale cell and mathematical model.

Research on osmosis behaviors of aluminum electrolyte in double-compartment cell;

The experimental results show that the penetrating materials in cathodes are very little at low current density in the single-compartment electrolytic cell.

Above the status quo,the control standards and the volatilization mechanism of dissecting room formaldehyde pollution were analyzed;then,the various control methods as well as their respective advantages and disadvantages were discussed.

In the field of medicine and biology, formalin is popularly used in the dissecting room as a effective and low-cost antiseptic.
