Measuring biodegradability of poorly soluble substances according to the standardized test methods where the carbon dioxide captured in the absorption solution is the main parameter is time consuming and needs manual analysis.To overcome these problems, it was used a modified closed apparatus consist of two bottlesreaction bottle where the biodegradability takes place and absorption bottle where the carbon dioxide produced by the microbial inoculum is trapped.For the measurement of trapped carbon dioxide it is utilize the fact that the barium carbonates precipitate, which is the result of simple chemical reaction, decrease conductivity of the absorption solution linearly.To allow synchronized measurement of 8-12 apparatuses a real-time monitoring interface for recording conductivity of 8-12 probes was constructed and tested with the standard substance glucose during 14 days of continual measurements.Self-developed interface showed its full applicability in the biodegradability testing.A substance with at least 80 ppm C may be assessed by this method.
