| Abstract: | In this paper, an ultrasound–acetic acid procedure for the simultaneous extraction and hydrolysis of carbohydrates in marine sediments prior to their colorimetric determination is described. The main advantage of the proposed procedure is the improved analytical accuracy achieved. Extraction and hydrolysis are quantitative since the oxidative reactions which cause the underestimation of the total carbohydrate amount are minimized. Moreover the procedure is fast, requiring only 5 h for the whole analysis (extraction, hydrolysis and colorimetric determination by the phenol-sulphuric acid method). The proposed procedure has recoveries generally higher than 80% and gives comparable results with the conventional 24 h HCl extraction. |
