1£©All calibration equations are written with an unrealistic number of significant figures. Standard deviations in the slope and the ordinate at the origin should be incorporated and all quantities should be expressed with the pertinent number of significant figures according to the IUPAC recommendations. ÆäÖÐÒ»×éÊý¾Ý£º I (mA) = -0.0544X-2.0313, R2 = 0.9983 2£©The same problem appears in Table 2. The values of the "obtained concentration" were totally unrealistic. The authors should be aware that a value of, for instance, 5.0039 implies that this quantity is know with an uncertainty of 0.002 % (!). 5.0039ÊÇtable2ÖеÄÒ»¸öÊý¾Ý Éó¸åÈËÊÇ˵ÎÒµÄÓÐЧÊý×Ö²»¶ÔÂð?

II) Linear equations in page 13 and Figures 7 and 8b should be rewritten incorporating the standard deviations in the slope and the ordinate at the origin and writing all quantities with the number of significant figures according to the usual IUPAC recommendations. Slopes in page 15 and all other quantities (in particular in Table 2) should be rewritten using the pertinent number of significant figures according to the usual IUPAC recommendations based on the above analysis of errors.
