Once the surgical procedure is complete, sevoflurane is discontinued, and the patient begins to recover. The elimination of sevoflurane from the body occurs primarily through exhalation. The patient continues to breathe out the residual sevoflurane until the concentration in the bloodstream reaches a safe level for awakening. This process typically leads to a relatively rapid and smooth recovery.

Solid water treatment chemicals also contribute to the removal of specific contaminants. For example, zeolites and activated carbon in granular form are effective adsorbents used to eliminate unwanted elements such as heavy metals and organic compounds. These adsorbents work by trapping contaminants within their structure, effectively improving the quality of water.


Antimicrobial additives are substances incorporated into plastic materials to inhibit the growth of bacteria, fungi, and other pathogens. They can be derived from natural sources, such as plant extracts, or synthesized through chemical processes. The most common types include silver ions, copper, zinc, and various organic compounds. These additives can be blended into the polymer matrix or applied as a coating, depending on the desired application.
