oa Diaphragm Cells for Chlorine Production

A symposium held in London in June, organised by the Electrochemical Technology Group of the Society of Chemical Industry, provided an opportunity for discussion of developments over the last ten years in the operation of diaphragm cells for chlorine production. Many of the papers presented outlined improvements in cell design and in diaphragm materials. Dimensionally stable anodes, made of titanium coated with a platinum-group metal oxide, are used in all the cells reviewed.
