Patent ID: 10201800

Abstract:
The present disclosure relates, according to some embodiments, reactive self-indicating adsorbent materials, methods, and systems. A system may comprise, for example, a reactive self-indicating adsorbent material, wherein the reactive self-indicating adsorbent material comprises at least one super paramagnetic particle and a semi permeable support, wherein the at least one super paramagnetic particle is configured such that at least one magnetic property of the at least one super paramagnetic particle changes upon contact with an adsorbate; and/or at least one detector configured and arranged to detect the at least one magnetic property. In some embodiments, a method for assessing the performance and/or remaining life of an adsorbent material may comprise (a) contacting a fluid comprising an adsorbate with the adsorbent material under conditions that permit the adsorbate to contact the at least one super paramagnetic particle, wherein a change in a magnetic property of the at least one super paramagnetic particle occurs upon contact with the adsorbate; (b) detecting the magnetic property of the at least one super paramagnetic particle; and/or (c) comparing the detected magnetic property to a reference to produce an assessment of the performance and/or remaining life of the adsorbent material.
