A polyelectrolyte is a polymer which, dissolved in water, ionizes and gives one poly-ion and small-size counter-ions. Thus, sodium polystyrene sulphonate is a typical poly-electrolyte. [Pg.165]

Osmotic pressure measurements of sodium polystyrene-sulphonate, with a molecular mass M = 4.5 x 105 have been made by Takahashi and Nagasawa,10 and the result is represented in Fig. 5.11. The abscissa is the mass-concentration... [Pg.166]

Quantitative rate data for reactions discussed in this section are given in Tables 3 and 4. The use of the ion [Ru(NH3)6] + as an outer-sphere reductant is much in evidence. The effect of sodium polystyrene sulphonate and sodium polyethylene on the rate of reduction of the series of complexes [Co(en)2(Cl)A] + (A = py, HjO, or NH3), [Co(en)2Cla]+, and [(NH3)6CoBrp+ has been investigated, for comparison with known effects in inner-sphere reactions. Though acceleration factors were found for both mechanisms, activation parameters reveal that for outer-sphere a lowering of Aff and for inner-sphere a more favourable AS are responsible. With [Ru(NH3)b] + in large excess, the consumption of horse heart ferricytochrome c obeys the rate law... [Pg.26]

NickeI(Il).— The rate constants have been measured for complex formation and dissociation with neutral and anionic ligands in the presence of polyelectrolytes [sodium polystyrene sulphonate, sodium poly(ethylene sulphonate), and poly-(ethylenimine) hydrochloride]. In the reaction with the murexide anion, the formation rate constant kt was decreased by the presence of either anionic or cationic polyelectrolyte, whereas the dissociation rate constant remained unchanged. With the neutral ligands (phen, bipy, and pada), however, the polyelectrolytes with hydrophobic residues enhanced kt (the value of k again being unchan ). It appears that the increase in kt is associated with a reduction in the activation enthalpy e.g. 13.5 kcal mol for bipy with no added polyelectrolyte but 11.2 kcal mol with 1.5x 10 equivl of sodium polystyrene sulphonate). The authors discuss their results in terms of the formation of polyelectrolyte-metal complexes but it is quite clear that the presence of innocent species can have large effects on the kinetics of metal complex formation - even with neutral ligands which apparently follow the normal mechanism.

A 66-year-old man hospitalised for severe abdominal pain had been previously treated for chronic renal failure and was treated with sodium polystyrene sulphonate and the spherical carbon adsorbent AST-120 [105 ]. The diagnosis was h5rpokalemic myopathy caused by accumulation of sodium polystyrene sulphonate in the colorectum. [Pg.334]

Field flow fractionation has been used to fractionate and determine the molecular weight of sodium polystyrene sulphonate" and polystyrene sulphonate (molecular weight range 6.6 x 10 to 6.9 x 10 ). [Pg.38]

Fig. 8. Specific conductance of sodium polystyrene sulphonate solutions in the presence of NaCl [29]. Number average molecular weight 2.0 x 10, 25 °C, 1 kHz. The extrapolation of the specific conductance to infinite high frequency was carried out for the solutions in the absence of added salt, assuming the linearity between specific conductance and reciprocal square root of frequency, but the error was within 0.4 %. NaCl concentrations are 0, 0.005, 0.01, 0.02, 0.05 and 0.1 N from bottom to top. Both solid and broken lines are drawn in parallel, respectively.
