A sodium fluorescein solution was introduced into an upfeed serpentine and a horizontal automatic watering rack manifold. Water samples were collected from nine drinking valves on each manifold prior to and after flushing at 12 pounds per square inch water pressure for 15 seconds, one minute, and five minutes. The water samples were assayed for fluorescein and it was found that the chemical was effectively removed by flushing from the upfeed serpentine manifold, while significant levels of fluorescein remained in the horizontal manifold even after five minutes flushing.
将荧光素钠溶液引入上行蛇形管和水平自动浇水架歧管中。在以每平方英寸12磅的水压冲洗15秒、1分钟和5分钟之前和之后,从每个歧管上的九个饮水阀采集水样。对水样进行荧光素检测,发现通过冲洗可有效去除上行蛇形管歧管中的该化学物质,而即使冲洗五分钟后,水平歧管中仍残留有大量荧光素。
