摘要
The paper deals with the removal and control of red tide algae,Phaeoecystis globosa and Alexandrium tamarense by biquaternary ammonium salt algaecide.The results show that the efficient concentration of biquaternary ammonium salt to control the two algaes in 96 h is 0.8 mg·L^(-1)and 0.4 mg·L^(-1),respectively.It is found that biquaternary ammonium salt has high efficiency and longer duration of action in the removal and control of algae.Biquaternary ammonium salt might be an excellent algaecide to control HAB.
