摘要
采用离子色谱法对新汴河河水进行测定分析,探究了新汴河中氟离子的分布特征,结果表明:新汴河F-质量浓度与Ca^(2+)、Mg^(2+)、Na^(+)、K^(+)、Cl^(-)、SO_(4)^(2-)质量浓度存在相关性,其中ρ(F^(-))与ρ(Ca^(2+))呈负相关,两者关系可表示为Y_(F^(-))=-0.04×X_(Ca^(2+))+3.01。ρ(F^(-))与ρ(Mg^(2+))、ρ(Na^(+))、ρ(K^(+))、ρ(Cl^(-))、ρ(SO_(4)^(2-))呈正相关,可分别表示为,Y_(F^(-))=0.06×X_(Mg^(2+))-0.51,Y_(F^(-))=0.004×X_(Na^(+))+0.39,Y_(F^(-))=0.63×X_(K^(+))-4.36,Y_(F^(-))=0.006×X_(Cl^(-))-0.28,Y_(F^(-))=0.004×X_(SO_(4)^(2-))-0.28。新汴河上游氟离子质量浓度较高,平均质量浓度为1.27 mg/L,下游氟离子平均质量浓度为0.65 mg/L。上游氟离子质量浓度高于下游氟离子质量浓度可能与引河汇入有关。新汴河较高浓度的氟离子主要受含氟矿物的溶解及工业燃煤影响,农业生产对氟离子聚集发挥着次要作用。
The water of Xinbian River was measured and analyzed by ion chromatography,and the distribution characteristics of fluoride ions in Xinbian River were explored.The results showed that:F-is correlated with Ca^(2+),Mg^(2+),Na^(+),K^(+),Cl^(-),SO_(4)^(2-),among which F^(-)and Ca^(2+)is negatively correlated,the relationship between the two can be expressed as Y_(F^(-))=-0.04×X_(Ca^(2+))+3.01;F^(-)is positively correlated with Mg^(2+),Na^(+),K^(+),Cl^(-),SO_(4)^(2-),which can be expressed as Y_(F^(-))=0.06×X_(Mg^(2+))-0.51,Y_(F^(-))=0.004×X_(Na^(+))+0.39,Y_(F^(-))=0.63×X_(K^(+))-4.36,Y_(F^(-))=0.006×X_(Cl^(-))-0.28,Y_(F^(-))=0.004×X_(SO_(4)^(2-))-0.28.In the upstream of the Xinbian River,the average concentration of fluoride ion is 1.27 mg/L,while in the downstream,the average concentration is 0.65 mg/L.The higher fluorine ion concentration in the upstream than in the downstream may be related to the inflow of the Yin River.The higher concentration of fluoride ions in Xinbian River is mainly related to the dissolution of fluorine-containing minerals and the impact of industrial coal burning,and agricultural production plays a secondary role in fluoride accumulation.
