ABSTRACT
OBJECTIVE:To prepare Ferulic acid/K/β-CD/metal organic framework (FA/K/β-CD/MOF) inclusion,and to opti-mize its preparation technology. METHODS:K/β-CD/MOF was synthesized by solvothermal method as inclusion material. Using FA as main component,FA/K/β-CD/MOF was prepared by grinding method. The preparation technology was optimized by orthogo-nal test using mole ratio of main component-inclusion material,grinding time,dropping time and inclusion temperature as factors, inclusion rate as index. Prepared FA/K/β-CD/MOF was indentified by IR spectrum and DSC,and inclusion rate and dissolution rate were determined. RESULTS:Optimized preparation technology was as follows as mole ratio of main main component to inclusion material 3∶1,dropping time 60 min,inclusion temperature 40 ℃,inclusion time 60 min. Prepared FA/K/β-CD-MOF had already formed a new kind of phase,and its average inclusion rate was(18.0±1.6)%(RSD=0.9%,n=6);its solubility was 15 times as much as FA(9.582 mg/ml vs. 0.647 mg/ml). CONCLUSIONS:FA/K/β-CD/MOF is prepared successfully;and the preparation tech-nology is reasonable and feasible.
ABSTRACT
The innovation of the specialism's development of computer science and technology needs to change the concept of education,and to create the curricular system that focuses on the creative ability of students.Furthermore,in order to make students to grasp theory,reinforce application and protrude ability,the curricular system of computer science and technology needs to be established.Cultivating the innovative ability of computer major students,we can adopt some major measures,such as setting up innovative ability teaching system.The helpful discussion and some personal opinion are presented in the paper aiming at the function of university computer lab in the cultivation of undergraduate creativity and practice.
