Anion exchange energies

The fact that the site occupation in magnetite is opposite to that of spinel arises from the interaction of the d elecU ons on die cations with the suiTound-ing anions. The energy for the exchange...

Several cases of interaction between anion exchange resins and nitric acid causing rapid release of energy or explosion have occurred [1]. The cause has been attributed to oxidative degradation of the organic resin matrix and/or nitration of...

Effect of the salt molecular mass (MB) on the cation transport number (C) in the corresponding solution effective solute (tB) and water (%) transport numbers surface resistances (rc, ra) of, and counterion transport numbers (tc+, ta ) in cation- and anion-exchange membranes specific electric energy consumption (e) in the case of 90% salt recovery at 1 A, and maximum solute concentration theoretically achievable in the concentrating stream (CBCmax). Note NaCl, sodium chloride Na-A, acetate Na-P, propionate Na-L, lactate. 

Here, Epro is the energy for the production of a certain amount of acid and base, I is the current passing through the stack, Nceu is the number of cell units in a stack, A n is the cell unit area, C and C are the concentration and the average concentration in a cell, A is the thickness of the individual cells, and A is the equivalent conductivity, r is the area resistance, , is the current utilization, R is the gas constant, T the absolute temperature, F the Faraday constant, and ApH is the difference in the pH value between the acid and base, the subscript p refers to product and the subscript i refers to salt, acid and base, The superscripts am, cm, and bm refer to the cation-exchange, the anion-exchange, and the bipolar membrane, the superscript out and in refer to cell outlet and inlet, Q is the total flow of the acid or base through the stack and t is the time. 

Figure 4. Log [H2 generation rates] plotted against 1/T. The solution, 7.5 wt% NaBH, 1 wt% NaOH, 91.5 wt% H20, was catalyzed by 0.25g of 5 wt% Ru supported on IRA 400 anion exchange resin at 40°C, 32.5°C, 25°C and 0°C. The apparent activation energy calculated from the slope of the straight line was 56 kJ mole-1.

Neither inhibitors of glycolysis, nor uncouplers of cellular energy-releasing processes had any significant effect on the rate of vanadate influx. Phosphate, which is readily taken up by the cells inhibited vanadate influx. Sulfate is not accumulated by the cells, and neither sulfate nor chromate appreciably inhibited vanadate influx at concentrations up to 10.9 mM and 200, uM, respectively. Most significantly, inhibitors of anion exchange across the human red cell membrane such as DIDS (4,4 - diisothiocyanostilbene - 2,2 -disulfonic acid) were also found to block vanadate transport into vanadocytes.
