A quick method for maintaining the molarity of NaOH solution during continuous etching of CR-39

An extended study of the etching characteristics of CR-39 detectors

“…KOH solution confirms good performances as etchant in terms of the reproducibility of the etching process: this result differs from the one concerning NaOH (Khan et al, 2002).…”

“…Some authors (Khan et al, 2002) observed sensible variations of NaOH solution conductivity due to the contribution of CR-39 by-products during the etching process: in particular it has been noted that after 6 h at 70 C the conductivity of the blank solution (NaOH 6 M) increased of about 13% while the one employed for an etching process had a conductivity value about 45% higher. For this reason the experimental protocol provided a further check of the conductivity at the end of the etching, in order to investigate this phenomenon in KOH solutions.…”

Application of Organic Polymer in the Identification of Radioactive Pu Isotopes

“…The concentration of the etchant increases by using the same etchant for a longer duration due to water evaporation. 6 During chemical etching, hydroxide ion hydrolyses the carbonate ester bonds and the release of polyallylalcohol from the polymer network occurs.…”

Research and applications of nuclear tracks: Developments in Pakistan and global comparison

“…The same procedure was also investigated by PINSTECH group. Their main focus was on properties and effects of etch products in etchants [16][17][18]. A latent track can be divided into three volumetric regions along the radial direction.…”
