“…The former method was applied to the determination of CO 2 in atmospheric air and human breath. This allowed the determination range of 98-1,570 mg m −3 , and a limit of detection of 2.9 mg m −3 [20].…”

“…Compared with the method developed by Lan et al [20], which provided a determination range of ca. 98-1,570 mg m −3 and a limit of detection of 2.9 mg m −3 for CO 2 , our method promises a wider linear range for the determination and is more sensitive.…”

“…Many environmental pollutants have been successfully determined with this technique [17]. However, to the best of our knowledge, only two works have been reported that are based on the use of flow-injection CL to determine chemical oxygen demand (COD) [18,19], a parameter similar to TOC indicating the sum of organic compounds, and another to determine CO 2 [20]. No CL system has been applied to the determination of TIC or TOC.…”

“…Based on this finding and the technique of potassium persulfate oxidation [8], a new method for determining carbon fractions was established. The current method compared with the method developed by Lan et al [20] for the determination of CO 2 is more sensitive and more resistant to foreign interferences. The method has successfully been applied to the determination of TIC and TOC in water.…”

“…No CL system has been applied to the determination of TIC or TOC. In the works of Lan et al [20,21] and Xiao et al [22], the enhancement effect of CO 2 or CO 2À 3 on the CL reaction of H 2 O 2 -luminol was investigated in the presence of heavy metal ions, thereby CL methods for the determination of CO 2 and Co 2+ were developed, respectively. The former method was applied to the determination of CO 2 in atmospheric air and human breath.…”

In the presence of carbonate and uranine, the chemiluminescent intensity from the reaction of luminol with hydrogen peroxide was dramatically enhanced in a basic medium. Based on this fact and coupled with the technique of flow-injection analysis, a highly sensitive method was developed for the determination of carbonate with a wide linear range. The method provided the determination of carbonate with a wide linear range of 1.0×10−10 -5.0×10 −6 mol L −1 and a low detection limit (S/N=3) of carbonate of 1.2×10 −11 mol L −1 . The average relative standard deviation for 1.0×10 −9 -9.0×10 −7 mol L −1 of carbonate was 3.7% (n=11). Combined with the wet oxidation of potassium persulfate, the method was applied to the simultaneous determination of total inorganic carbon (TIC) and total organic carbon (TOC) in water. The linear ranges for TIC and TOC were 1.2×10 −6 -6.0×10 −2 mg L −1 and 0.08-30 mg L −1 carbon, respectively. Recoveries of 97.4-106.4% for TIC and 96.0-98.5% for TOC were obtained by adding 5 or 50 mg L −1 of carbon to the water samples. The relative standard deviations (RSDs) were 2.6-4.8% for TIC and 4.6-6.6% for TOC (n = 5). The mechanism of the chemiluminescent reaction was also explored and a reasonable explanation about chemical energy transfer from luminol to uranine was proposed.
