| Abstract: | The factors that effect absorption of cadmium in wastewater include the solution temperature and cadmium concentration, pH value and absorption time. The results show that super micro - milling rice bran indicates excellent absorption effects on cadmium in wastewater with more than 90% absorption rate. The best absorption conditions are 5g/L of dosage of super micro - milling rice bran and 30℃ of temperature and 3 of pH value and 30 minutes with less than 20mg/L of cadmium concentration. |
