Possible to use alcali solution to discharge static electricity?

It is not uncommon to use an electrically conductive bracelet, connected to a flexible electrically cable, to conduct electricitity between a person and the table he/she is working on, so that sparks can't jump between the person and things touching the table. This is close to what you are suggesting. The bucket of alkali solution, though, is not necessary. Only electrical contact between oerson and table is required. In cases where stray voltages may cause problems, e.g. in roll-to roll machinery, either cables with conductive brushes, ion generators, or even radioactive bars are used to provide conductive paths to dissipate static charge.
