A Review of Selected Electrochemical Technologies to Manage Chlorine Dioxide Generator Saltcake and its (PPT)Conversion to Useful Chemicals (PPT)

摘要

Chemical and electrochemical processes are available and are being used to address the reduction or reprocessing of CIO2 generators saltcake. a) Separation of acid (NaHSO4) and neutral (Na2SO4) components via saltcake metathesis. b) Electrochemical saltcake splitting to valuable NaOH and usable acid mixture (NaHSO4/H2SO4). c) Reduction or total elimination of saltcake generation via electrochemical conversion of chlorate feed to chloric acid.
