To address physicochemical factors of yellow clay for removing Cochlodinium polykrikoides blooms, the correlation of removal efficiency with mineralogical characteristics of yellow clay collected from various areas was surveyed. Yellow clay from different localities showed the wide range of chemical compositions SiO₂ : 43∼71%, Al₂O₃ : 13∼26%, Fe₂O₃ : 5∼14%, MgO : 0.4∼1.8%, K₂O : 0.6∼3.3%, L.O.I.(Loss of Ignition) : 4.5∼15%. The mineral compositions of yellow clay were mainly consisted of quartz and feldspar including small amounts of kaolinite, chlorite, and Fe-oxides. The result of size analysis showed that 6Φ(31∼16㎛) and 7Φ(16∼8㎛) were dominated sizes. The zeta-potential were in the range of –4.1∼-20.7㎷(average -13.7).
As increasing removal efficiency of C. polykrikoides, contents of Al₂O₃, Fe₂O₃ and L.O.I. in yellow clay increased, whereas SiO₂ content decreased. Furthermore, the amounts of silt mineral and small particle were high when the removal efficiency was high.
According to factor analysis using principle component analysis, two components of factor 1 and factor 2 showed 79% of the total variance, which is related to cohesion and adsorption. Inducing cell lysis of C. polykrikoides by cohension and adsorption between C. polykrikoides and yellow clay.
