TL;DR: Agarose can be activated by adding cyanogen bromide, dissolved in acetonitrile, to beads suspended in a solution of sodium carbonate, and the necessity for manual titration and the use of a pH meter are eliminated.

TL;DR: Analysis of absorption spectra of a yellow color solution resulting from the reaction of persulfate and iodide in the presence of sodium bicarbonate reveals an absorbance at 352 nm, without significant interferences from the reagent matrix.

TL;DR: In this paper, a method is proposed to estimate the point of zero charge (pzc) of pure compounds which can be described accurately by the surface ionization model of amphoteric oxides.
Abstract: A method is proposed to estimate the point of zero charge (pzc) of pure compounds which can be described accurately by the surface ionization model of amphoteric oxides. It is demonstrated that under the limiting conditions of “infinite” mass/volume ratio, the pH of the system will approach pH ∞ = 1 2 ( p K 1 + p K 2 )  pzc . Experimental values of the pH of the oxides of titanium, aluminum, a silicon suspended in a closed aqueous system exhibited the existence of a constant pH at high mass fractions. This limiting pH is found to be a reasonable estimate for the point of zero charge of each oxide.

TL;DR: The analysis of aqueous H 2 O 2 at concentrations as low as 1 μM is conveniently done by the I 3 - method, which is based on the spectrophotometric determination of I 3, formed when H 2 o 2 is added to a concentrated solution of I -. At 351 nm, E max (I 3 - ) was measured to be 26 450 M -1 cm -1.

At 351 nm, E max (I 3 - ) was measured to be 26 450 M -1 cm -1 . By contrast, an apparent value of 25 800 M -1 cm -1 was determined from a calibration of the I 3 - method against titration by permanganate. The difference could only be partially accounted for by the equilibrium between I 3 - , I 2 , and I -

TL;DR: In this paper, the surface groups of active carbons can also be characterized by immersion calorimetry and the variation of the pH of the point of zero charge with the total oxygen content of the surface.
