Title: Removing method for chromic acid in electrolyte
Inventor: ARIGA KAZUO
IPC: C25F7/02
Filed: 1979-10-17
Abstract: PURPOSE: To reduce the useless labor and processing cost with regard to removal of chromic acid in an electrolyte by separating a Cr containing concentrated solution from an electrolyte containing nitric acid from which Cr acid is produced, and by performing dehydration-filtering after reducing Cr acid by adding an iron electrolytic eluate to said separated solution.  
     CONSTITUTION: The electrolyte that consists essentially of nitrate and produces Cr acid is introduced from processing device 1 to concentration tank 5, where it is separated into a dilute solution and a concentrated solution containing many Cr acid and unsolved substances; and the concentrated solution is introduced to reducing tank 8, where a solution of ferrous salt, i.e. iron electrolytic eluate 10 from iron electrolyte tank 9 (taking a solution of nitrate as an electrolyte and iron as an anode for electrolyzation) is added and Cr acid is reduced. Then, the reduced concentrated solution is separated into a filtrate and slip by dehydrating filter 12 and while the Cr acid is exhausted out as slip, the filtrate is circularly used as an electrolyte. Thus, the labor and processing cost of the Cr acid processing can remarkably be reduced.

The frequency and the output frequency (f) of the VCO29 are multiplied by a multiplier 27, and the result passes an LPF26 to obtain a signal having a frequency 2fd. An oscillation frequency f0 of a master clock oscillator 21 and the frequency (f) are multiplied by a multiplier 22, and the result passes an LPF23 to obtain a frequency f0-f, and this frequency is multiplied in a multiplier 24 by 2, and the phase of the signal resulting from this multiplication is compared with that of the output signal of the LPF26 by a comparator 25, and the comparison output passes an LPF28 to control the VCO29.
