As for the Cr~(3+), it does not need to change the characteristic of diatomite,the rate can attain 90%. Besides, the model of diatomite adsorbing Cr~(3+) matches the Freundlich adsorption isotherms well.

- 對于Cr~(3+)來(lái)說(shuō),由于硅藻土吸附重金屬的能力很強,所以不用改性硅藻土對其的去除率就能達到90%25,硅藻土對Cr~(3+)的吸附模型較好的符合Freundlich吸附等溫式。
