“…This explanation is consistent with a previous observation that PP powder has a high affinity for anionic polyelectrolyte adsorption. 16 Thus, less significant adsorption of PR on b-PANI may result from a repulsive electrostatic interaction between PR and b-PANI. However, still some amounts of PR are seen to be adsorbed on the b-PANI and particularly on n-PANI.…”

“…13 The wide range of associated electrical, electrochemical and optical properties coupled with good stability make PANI potentially attractive for application in various fields. Besides the many other interesting properties, PANI exhibits relatively high surface area and porosity 14,15 and is reported to be utilized as adsorbent for adsorption of protein 16,17 and DNA. [18][19][20] Polypyrrole (PP) colloids stabilized by polyvinylphosphate dopant are also shown to adsorb metal ions from aqueous solutions.…”

Chemically synthesized conducting polyaniline (PANI) was investigated as adsorbent for its possible application in the removal of organic dyes, such as methylene blue (MB) and procion red (PR) from their aqueous solution. PANI adsorbent behaves as a charged surface upon post-synthesis treatment of the polymer with acid and base. The adsorbent thus treated shows a high selectivity for the removal of dyes in the adsorption process. The Langmuir adsorption isotherm was used to represent the experimental adsorption data. The cationic dye, MB can be preferentially removed by the base-treated PANI while the anionic dye, PR is predominately removed by the acid-treated one. These observations were further evidenced from the measurements of molar conductance and pH of the dye solutions employed for adsorption. The finding can be explained considering the electrostatic nature of adsorption coupled with the morphology of the PANI surface thus treated.

The enzyme beta-glucosidase was attached covalently to the inner surface of nylon tubing. Flow kinetic studies were carried out at a range of temperatures, pH values, flow rates, and substrate concentrations. Various tests showed that the extent of diffusion control was negligible. At 25 degrees C the Michaelis constant was 33.4 mM, not greatly different from the value for the enzyme in free solution. The pH dependence was similar to that for the free enzyme. The Arrhenius plots showed inflexions at about 22 degrees C, as with the free enzyme, the changes in slope being small at the pH optimum of about 5.9 and becoming much more pronounced as the pH is increased or decreased. The immobilized enzyme is more stable than the free enzyme, both on storage at low and higher temperatures, and its reuse stability is greater.

The effects have been evaluated of up to 30% (v/v) of methanol, ethanol, 2-propanol, tert-butylalcohol, dimethylsulfoxide, sulfolane, acetonitrile, dimethylformamide, N-methyl-2-pyrrolidone, hexamethylphosphoramide, tetrahydrofuran, dimethoxymethane, diglyme, and dioxane on horse liver alcohol dehydrogenase-catalyzed reduction of the representative ketone cyclohexanone. The most viable solvents are those shown in italics on the above list.
