The term 'adsorbent' is primarily used in technical, scientific, and industrial contexts in both Brazil and the USA. It is not commonly used in everyday conversation. In Brazil, it appears frequently in environmental engineering, water treatment, and chemistry textbooks and professional settings. The distinction between 'adsorption' and 'absorption' is important in Portuguese technical vocabulary, just as in English.
