岩溶地下水样品Ca2+、HCO-3野外测试值与实验室测试值对比研究
Contrast study of Ca2+ and HCO-3 concentration in karst-water samples between field test and laboratory test values
摘要
Abstract
In order to grasp the differences of Ca2 + and HCO -3 concentration in karst water between field test and laboratory test values,85 groundwater samples collected from Zunyi,Hechi and Loudi City were ana-lyzed.The results show that 88.2% of the sample sites of Ca2 + have field values greater than the experimen-tal values,while 64.7% of the sample sites of HCO -3 have field values greater than the experimental values. Using the ratio method,(CaY/CaS )is of an average value of 1.11,mainly concentrating between 1.0 and 1.2,accounting for 70% of the total,and (HCO 3Y/HCO 3S )with a average value of 1.02,mainly concentrat-ed in between 0.95 and 1.1,accounting for 75% of the total.Under certain conditions of the laboratory test error,artificial random error has some impact on the result of the test.The results provide basic data to im-prove the quality of field surveys of underground water.关键词
