Effect Of Substituents

Electrocatalytic decolorization of the arylazo pyridone dyes has been investigated in the presence of sodium chloride using DSA Ti/PtOx electrode in the diluted sodium hydroxide. Decolorization can be attributed to the indirect oxidation of the investigated dyes by the electrogenerated hypochlorite formed from the chloride oxidation. Electrochemical decolorization has been investigated for the different sodium hydroxide concentration in the range from 40 mg dm-3 to 4 g dm-3, sodium chloride concentration in the range from 15 to 40 g dm-3, agitation speed in the range from 150 to 500 rpm, currents in the range of 100 to 250 mA, and dye concentration from 5 to 20 mg dm-3. The optimum electrolysis conditions have been suggested. Effect of substituents on the reaction rate has also been studied.

ABSTRACT Viruses were characterized by their adsorption to DEAE-Sepharose or by their elution from octyl-Sepharose by using buffered solutions of sodium chloride with different ionic strengths. Viruses whose adsorption to DEAE-Sepharose was reduced most rapidly by an increase in the sodium chloride concentration were considered to have the weakest electrostatic interactions with the solids; these viruses included MS2, E1, and φX174. Viruses whose adsorption to DEAE-Sepharose was reduced least rapidly were considered to have the strongest electrostatic interactions with the column; these viruses included P1, T4, T2, and E5. All of the viruses studied adsorbed to octyl-Sepharose in the presence of 4 M NaCl. Viruses that were eluted most rapidly following a decrease in the concentration of NaCl were considered to have the weakest hydrophobic interactions with the column; these viruses included φX174, CB4, and E1. Viruses that were eluted least rapidly from the columns after the NaCl concentration was decreased were considered to have the strongest hydrophobic interactions with the column; these viruses included f2, MS2, and E5.

Young barley plants, Hordeum vulgare cv. Chevron, were subjected to a sodium chloride concentration of 100 m-equiv/l. In a "continued" treatment, the salinity stress was maintained for 15 days. In a "removed" treatment, sodium chloride was removed from the substrate after 5 days, and the subsequent response was studied over a period of 10 days.

Stichococcus Bacillaris

Stichococcus bacillaris has been grown under conditions of varying ionic concentrations. Sodium chloride appears to be the dominant compound in determining growth of this euryhaline alga and from the reaction to increased sodium chloride concentration it is postulated that S. bacillaris is a freshwater organism which can tolerate high salinities. Some morphogenetic effects of high salinity are described.
