[ Analytical Chemistry ][ Environmental Analysis ]
Super Absorbent Polymer (Acrylate Type)
Capable of absorbing as much as 400 times its own weight of water!
What is a Super Absorbent Polymer?
A Super Absorbent Polymer is a polymer characterized by rapid water absorption and swelling when it comes into contact with water, and capable of absorbing as much as several hundred times its own weight. It also has the characteristics of retaining most of the absorbed liquid even if pressure is applied. Therefore, it is used as a disposable diaper or sanitary goods and applied to the fields of agriculture, medicine and civil engineering as water absorbent, moisture absorbent, gelling agent and humectant. Its application as a research reagent is also becoming widespread.
This product is a partially neutralized cross-linked poly (acrylic acid) and forms a relatively hard gel by absorbing as much as 400 times its own weight of water. It is insoluble in water and organic solvents.
[Example of use]
Used for Various Purposes
For pretreatment of environmental water samples in rapid analysis of stable nitrogen isotope ratio.
(Described in the literature below by Dr. Nishikawa, National Institute for Environmental Studies)
The water sample can be analyzed simply and rapidly as a solid sample by absorbing and immobilizing into Super Absorbent Polymer.
