摘要

传统的水质监测是以污染物质在水中的瞬时浓度来反映水质状况

耗时耗力。通过离子交换树脂球对西湖龙泓涧溪流中离子的持续吸附试验研究了树脂球在水质监测中的应用。结果表明

再生树脂球阴离子(NO

-N

-P)的回收率最小值为95.91%

而且在不同处理下其回收率的差异性不显著(p=0.105>0.05);阳离子(NH

)在低浓度时回收率超过100%

高浓度时约为90%

说明再生树脂球可用于水体中离子的吸附。各种离子的树脂球累积吸附量(RAQ)与流量呈显著正相关(R

＝0.59

0.47

0.50

0.05)

且NO

-N的RAQ和离子浓度与水体流量之积呈显著正相关(R

＝0.46

0.05)

初步表明树脂球可以用于水体中氮和磷尤其是NO

-N的监测。

Abstract

Traditional monitoring on water quality is mainly carried according to the instantaneous concentration of pollutants in river

which is time consuming and labor cost. A method based on reuse of ion-exchange resin capsules was evaluated for continuously adsorbing ions in the Longhongjian stream discharged into the West Lake of Hangzhou City. Results showed that the recovery rates of reuse-resin capsule were greater than 95.91% for both NO3- and PO43-

but the differences among treatments were not significant. The recovery rate of reuse-resin capsule for NH4+ was greater than 100% in low concentration and 90% in high concentration. Significant correlations existed between resin capsule cumulative adsorption(RAQ) value and flow in all kinds of ions(R2=0.59

0.47 and 0.50

respectively

p<0.05). Moreover

there was a significant positive correlation(R2=0.46

p<0.05) between RAQ of NO3--N and concentration of NO3--N and water flow

indicating that resin capsules can be used in water monitoring of nitrogen and phosphorus

especially NO3--N.
