On the photolysis of alkylated naphthalenes in aquatic systems
Review articleOpen access

AbstractThe photodegradability in aquatic systems of some alkylated naphthalenes and related compounds was studied using a high-pressure mercury lamp. The rate constant and half-life of their degradation were estimated in distilled water. From the results performed in artificial seawater, which served as a marine environmental model, the rate of photolysis of alkylated naphthalenes increased several times over that in distilled water. This was especially observed for naphthalene. Therefore, sodium chloride, the main component of seawater, was estimated to be the cause of the enhancement, because the rate increased nearly proportionally to the concentration of NaCl in the system, with a correlation coefficient of 0.995 for 2-isopropylnaphthalene.
