Tap water was collected from Jinan in China. A barrel made of polyethylene with volume of 25L was
used to collect the water. Three adsorption column filled with activated carbon, haydite and quartz sand
were p repared to remove organic pollutants in tap water. All of column had a filler volume o f 2L. 20L
collected tap water was pumped into column by a peristaltic pump and the contact time was controlled in
1h [18]. In this experiment, we used sample 1, sample 2 and sample 3 to represent water samples treated
by activated carbon, haydite and quartz sand column respectively, corresponding to their raw water
sample a, b and c. All water samples were adjust to pH
