In this study, a new method of mercury reference material with new additives was developed. Rice powder was used as material substance. Instead of using CS2 coating solution, which previous studies have used, halogen solutions, such as CCL4, CH2CHCH2Br and CH3I were used in this study as new additives.The coating solution is an important factor in reference material development, since it improves homogeneity and stability. This method can improve mercury detectability and homogeneity as adsorption capacity is increased using various coating solution. Within-bottle and between-bottle homogeneity tests were conducted and the F-test results were compared using ANOVA technique. |
