objective: to study the direct drying oven drying method was developed for the determination of total soluble solids in drinking water. Methods: using water bath to dry method and drying oven drying method two kinds of methods determination of total soluble solid content in drinking water, and the comparison. Results: the data are drying oven drying method directly below the water bath to dry method, two methods for matching test, significant differences between the results (P < 0.05). Conclusion: drying box direct drying method is simple, less interference factors, can be used for the determination of a large number of samples.is worth promoting.
