摘要：
Our objective was to find out, if two different methods for determination of water quality indicators-spectrophotometric (SPM) and distillation-titration (DTM) - have comparable results. Distillation-titration method was done according to Peoples at all. (1986) and spectrophotometric method was done according to Hach-Lange methodology. Water sampling was realized in Jizera Mountains on three respectively six sites. Results from both methods were compared within one-way analysis of variance (ANOVA) in combination with Tukey's test and graphic processing into a chart, which are supplemented by tables. According to fixed standard deviation just two of comparisons of SPM and DTM are above the significant level, so both methods are comparable.
