This paper studied the removal efficiency of the red tide algae by silver ions.The results showed that silver ions can control developing of the red tide algae effectively in the range of concentrations: 0.125 to 0.25 mg/L.But the time of control is short.For this reason,we made a glass algicide containing silver ions.The silver ions are gradually elluted from the algicide as it dissolve when it is put into water.The silver ions can kill red tide algae and the time of control is prolonged.Morever,The paper studied the surplus silver ions concentration after the glass algicide acted with red tides and the influence of the silver ions to the environment.

本文简要介绍了中山市在国家环保总局"十五"环境规划期间做为第一批工业污染源全面达标试点城市,环境监测部门发挥出的重要职能和作用.对工业污染源全面达标验收工作做了全面而客观的总结和评估,为日后开展此项工作的兄弟单位提供了有益的经验和启示.

对连续流动分析仪测定水体中挥发酚的方法进行了研究。实验结果表明，在0～0.160mg/L线性区间内该方法具有较高的精密度和准确度，其最低检出限为0.001mg/L。与传统4-氨基安替比林萃取光度法相比，该方法具有自动进样、分析速率快、试剂耗量低等优点，可应用于大批量常规地表水样的分析。

油标准物质的选择是红外分光光度法测定水中油的重要环节,选择了两种不同的油标,采用红外分光光度法对水中油进行了分析,结果表明,油标不同,测量结果不同。理想的油标是从待测水样中提取,这样的油标的组成才能与被测水样中油的组分相同,红外光谱图基本相同,测定结果才准确可靠。
