摘要
用超声波(微波)辅助分光光度法研究硅藻土对亚甲基蓝吸附性能,在亚甲基蓝的剩余浓度为8.0×10-6g/ml范围内呈良好的线性关系。振荡时间、溶液pH、共存离子对吸附都有影响。实验表明:在超声波中超声8min,微波中低档辐照60s,pH=9.0的缓冲溶液和15mlNa4P2O7的条件下,吸附比较完全。
This method is based on the ultrasonic wave or microwave-assisted-photometry determination of the amount of ethylene blue remained in a water suspension after absorption by Kieselguhr. The linear range of calibration curve is 0～8.0×10-6g/ml.Vibration time. pH of solution. Coexisted ion have effect on the adsorbtion. The experiments show: when the solution is put in ultrasonic wave for 8 min, in the microwave of low efficiency for 60s ,the buffer solution is pH=9.0 and the volume of Na4P2O7 is 15ml, the adsorbtion is the best.
