| Abstract: | Research on monitoring total chrome in soil and water and wastewater by diphenylcarbohydrazide spectrophotometric method(A) and flame spectrophotometry(B) are finished.The merits of method A include high sensitivity and accuracy,the shortcomings are difficult to operate and long time needed.The merits of method B include quick and less disturbance,but the flame is not stable that will affect the results.The best flow of acetylene is found by experiments,it will get accurate and credible results,and extend the utilization scope of the equipment. |
