 Research interests

1.  Separation & purification of dilute organic solution

The reactive extraction behavior and mechanism is investigated for the wastewater treatment and separation of carboxylic acid. The rules of extractant used will be proposed for the product purification based on the removal of impurity.

2.  Waste water treatment for polar organic;

The solute in wastewater is extracted through the reactive extraction method, and the wastewater is satisfied with the national draining standard at solute concentration and COD value based on the result of extractants behavior in aqueous phase and rules of extractans and equipment used. We exploit new process to produce chemicals with high price by using the solute in wastewater.

3.  Intensification of separation process with physical field;

Effect of physical fields, e.g. ultrasound, magnetic and separation media, on the existed separation process is investigated. The potential properties and the rules of physical field used will be proposed based on characteristics of mass transfer area, mass transfer force and mass transfer coefficient in these fields.   

4.mass transfer properties 

The mass transfer characteristics in multi-solute system and short contact process are being studied for the new reactive extraction process, e. g. extractive fermentation and purification of bioproduct. The separation process can be intensified utilizing the kinetic properties to improve the separation ability. 

Current projects:

1.  Reactive extraction mechanism of carboxylic acid by chemical association;

2.  Manufacture technology of CMA (Calcium Magnesium Acetate )

3.  Waste water treatment for polar organic
