DID U KNOW series : Absorb vs Adsorb
From time to time, we receive questions from our customers and blog followers that relate to some of the technology and terms used in our packaging, promotions or digital communications. We thought this would be a great place to share additional insight into some of the questions we receive. This will be our first installment of “DID U KNOW? – Insights into our natural world by drTung’s.” This new blog segment is designed to provide readers with an “Aha moment”.
First on the list, the word adsorb. Yes—you read that right! NOT to be confused with “absorb”. Both of these verbs adsorb and absorb sound quite similar and their meanings both involve collecting a substance. However, the way they collect the substance is completely different and cannot be substituted for each other.
Let’s start with the easy one—absorb. Absorb means to soak up, like to soak up a spill with a paper towel. The towel absorbs water.
Adsorb, on the other hand, means to collect particles/molecules/gasses on a surface.
Adsorption then, is a surface phenomenon while absorption involves the whole volume of the material1
WHY DO WE WANT TO KNOW THIS DIFFERENCE?
It’s unlikely you will find a need to use the term adsorb in your daily life, as it is mainly a scientific term; however, there are many practical applications of adsorption that we don’t even think of—silica packets adsorb moisture to reduce humidity, gas masks adsorb poisonous gases, activated charcoal is an adsorbent used for overdose cases and water filtration.
Today we want to share how this word adsorb applies to DrTung’s products and how adsorption benefits your oral health.
