Sorbent
open-in-new
<h2 id="mechanism-of-action">Mechanism of action</h2> <p>Sorbents collect specific liquids or gases depending on the composition of the material being used in the sorbent. Some of the most common sorbents used to clean oil spills are made from materials that are both <a href="/facts/Oleophilic/AWpsR8Xe">oleophilic</a> and <a href="/facts/Hydrophobic/Ifya0CXQ">hydrophobic</a>, have high surface area through structural designs that include <a href="/facts/Porosity/UoyAJU8X">pores</a> and capillaries, and draw in liquid through <a href="/facts/Capillary_action/aa60yQ32">capillary action</a>.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> Sorbents may be used to collect undesirable <a href="/facts/Ion/wrbwhF3z">ions</a> and act like a reusable <a href="/facts/Ion-exchange_resin/z6KwlG8K">ion-exchange resin</a>, composed of charged layers of material that can be heated or otherwise treated to remove pollutants.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> In this and similar cases, pollutant particles are attracted to the sorbent through <a href="/facts/Electrostatic_forces/V0lR5NKv">electrostatic forces</a>.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> Some sorbents chemically bind to particles through chemical adsorption, or <a href="/facts/Chemisorption/QW4hL1RR">chemisorption</a>; this process is often more difficult to <a href="/facts/Reversible_process_(thermodynamics)/RtAnDT3C">reverse</a>.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> </p> <h2 id="examples">Examples</h2> <p>Sorbents come in various forms and materials, including: </p> <ul><li>Activated carbon, the most widely used sorbent, which has been known and manufactured since the 19th century,<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a></li> <li><a href="/facts/Molecular_sieve/Lzle8J7k">Molecular sieves</a>, commonly made from <a href="/facts/Zeolite/SNrXy4v2">zeolite</a>,<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a></li> <li><a href="/facts/Sponge/E9T2WFWA">Sponges</a>, which can absorb many times their own weight in liquid,<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a></li> <li><a href="/facts/Polypropylene/HM9PvoCz">Polypropylene</a> fiber mats, which can be employed to absorb oil,<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a></li> <li><a href="/facts/Cellulose/wYPafTU0">Cellulose</a> fiber products used for oil or chemical sorption,<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a></li> <li>The granular gel material in <a href="/facts/Diaper/62wCE4YW">diapers</a>, capable of absorbing multiple times its original weight in <a href="/facts/Urine/oNUYVtvX">urine</a>,<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a></li> <li><a href="/facts/Incontinence_pad/IpAhB871">Incontinence pads</a>, which may also incorporate <a href="/facts/Nonwoven_fabric/XeFJRS0B">nonwoven fabric</a> as a sorbent,<a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a> and</li> <li><a href="/facts/Desiccant/wD2YIcPc">Desiccants</a>, which attract water, thereby <a href="/facts/Drying/hRBvapJN">drying</a> (<a href="/facts/Desiccation/X6IUsM3R">desiccating</a>) surrounding materials.<a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a></li></ul> <ul><li>Willis, Thomas P.
