| Abstract: | The research of correlation between u.v. absorbance and organic matter content has been carried out for a long-term observation. The positive results enabled the construction of u.v. analyser for continuous absorbance measurements at 254nm. The instrument performance has been used in river reaches with organic pollution and in effluents from municipal and industrial sewage works, especially with humic, lignin and phenolic matter content. At present the u.v. analyser with automatical turbidity compensation for some types of water is tested. The application of u.v. control system under work conditions is significant for detecting the instant relative concentration changes of organic component in the tested water and for indicating harmful situations. For information the results of absorbance, oxidability and conversion factors are given. |
