|
||
unique challenges for cleanup because of its density and volatility. Use of
|
||
microorganisms may be a promising remediation method, however metabolism of TCE
|
||
results in acid buildup, which consequently impedes the ability of
|
||
microorganisms to perform this remediation. Polyvinylalginate (PVA) shows
|
||
promise as a useful shield for microorganisms carrying out bioremediation of TCE
|
||
by surrounding them in a protective biofilm-like layer, however, key information
|
||
is missing which relates diffusion of TCE or its metabolic products through PVA.
|
||
To measure the effective diffusion coefficient of H<sup>+</sup>
|
||
ions through
|
||
a PVA membrane cross-linked with boric acid and calcium ions, we used a modified
|
||
diaphragm cell. We found the effective diffusion coefficient to be 1.40 ×
|
||
10<sup>-5</sup>
|
||
± 1.91 × 10<sup>-6</sup>
|
||
cm<sup>2</sup>
|
||
s, a nearly
|
||
seven-fold decrease in diffusivity compared to protons in water, with an
|
||
unexpected significant but as of yet unquantified adsorption capacity. These
|
||
results suggest that polyvinylalginate is effective in slowing diffusion of
|
||
protons and buffering these acids produced by trichloroethylene metabolism, and
|
||
remains suitable for encapsulation of microorganisms involved in bioremediation.</p></div></section><footer><div class="container-fluid footer-contents"><img src=https://millironx.com/images/brandedbull_hufc3ef4d1bebcd0898802af378829db58_10410_0x95_resize_box_3.png></div></footer></main></div></div><script src=https://millironx.com/js/fontawesome.min.6bc2dd5568cf8d07e2b66db77311aec6816cce50f3477ceac674c711fd4ec8eb.js></script>
