摘要:
A filter-press type electrolytic cell is disclosed wherein sodium hypochlorite is produced by diaphragmless electrolysis of saline water. The filter-press electrolytic cell is compact and simple in structure, and operates with improved current efficiency, at a reduced cell voltage, and with less power and with minimal maintenance.
摘要:
Chlorine dioxide is produced by electrolysis of a solution of chlorite and by using a compact apparatus which provides continuously a uniform concentration of chlorine dioxide, which can be operated easily, which discharges a spent electrolyte that can be treated easily and which achieves highly efficient use of chlorite and high current efficiency.
摘要:
A photographic developer waste solution is electrolytically purified by adding to said waste solution chloride ion and bromide ion; or chloride ion, bromide ion and iodide or iodate ion under limited pH, temperature, anode current density and current concentration conditions.
摘要:
There is provided an image processing apparatus comprising: a common color reproduction range generation unit configured to select the data of interest as common color reproduction range data if the data of interest is determined by the first color reproduction range determination unit to fall within the color reproduction range of the first output device and is determined by the second color reproduction range determination unit to fall within the color reproduction range of the second output device; and a table correction unit configured to correct output values for respective grid points of a first color conversion table included in the image processing apparatus in accordance with differences between the reference values and the colorimetric values corresponding to the common color reproduction range data.
