Abstract

Sposób oczyszczania ultradźwiękowego w roztworach kwasu ortofosforowego z wykorzystaniem substancji redukującej, zdolnej wiązać zawarty w roztworze tlen, polega na tym, że do roztworu kwasu ortofosforowego wprowadza się kwas askorbowy, korzystnie w ilości 0,3 - 0,6%. Następnie roztwór poddaje się termicznemu odgazowaniu przez nagrzewanie do temperatury około 80°C z jednoczesnym nadźwiękawianiem i po ostudzeniu do około 70°C prowadzi się proces oczyszczania.The method of ultrasonic cleaning in orthophosphoric acid solutions using a reducing substance that is able to bind the oxygen contained in the solution is that ascorbic acid is introduced into the orthophosphoric acid solution, preferably in an amount of 0.3 - 0.6%. Then the solution is subjected to thermal degassing by heating to a temperature of about 80 ° C with simultaneous sonication and after cooling to about 70 ° C a purification process is carried out.
