Moisture Balance Helps Test Alkali Hydroxide Absorbents for Color Change

Alkali Hydroxide Absorbents Change Color Independent
Alkali Hydroxide Absorbents Change Color Independent of Their Moisture Content

This study tried to establish a correlation between the presence/absence of moisture and color change in alkali hydroxide and alkali hydroxide free absorbents.  Samples of both types of absorbents were tested using a moisture analyzer.  The moisture content was determined and the color change during drying was observed.  It was noted that color change did not happen even when the water retention was higher in the absorbents.  However it was observed that with increasing concentrations of Alkali Hydroxide the color change on drying was delayed.

About Bob Sandor

Bob began working as a chemist in 1987 and remains a science geek to this day. After his PhD he worked on the bench in materials and inorganic chemistry for 10 years. He then took on a love for marketing and sales. He combined his passion for science and business and took entrepreneur general management positions in large corporations like Hoecsht Celanese now Sanofi Aventis, Bel-Art and Smiths Detection. There he learned what it would take to run a business and finally Tovatech was co-founded in 2006.
