国贸专业大学生就业现状与意向调查研究——以湘南学院为例

据麦可思2013年中国大学生就业报告显示,国贸专业为黄牌警告专业,国贸专业毕业生就业情况堪忧。通过对湘南学院国贸专业在校生进行问卷调查,结合近几年国贸专业毕业生资料进行对比分析,认为:从学校方面而言,应加强实践教学,提升学生专业认知度,加强就业指导,提高就业质量,加强校企合作,建立见习实习基地,拓宽就业渠道,加强创业平台建设;对学生而言,则要正确定位,合理预期,积极参加专业实践,加强专业认知,结合市场需求,提升就业能力。     

Kinetics of 2,4-dichlorophenol dechlorination by Pd-Fe bimetallic nanoparticles in the presence of humic acid

The remediation of groundwater which contains chlorinated organic compounds （COCs） by nanoscale bimetallic catalysts has received increasing interest in recent years. This report presents the dechlorination of 2,4-dichlorophenol （2,4-DCP） by Pd-Fe bimetallic nanoparticles in the presence of humic acid （HA） to investigate the feasibility of using Pd-Fe for the in situ remediation of contaminated groundwater. Our experimental results indicated that HA had an adverse effect on the dechlorination of 2,4-DCP by Pd-Fe nanoparticles. The rate constant k values of 2,4-DCP dechlorination were 0.017, 0.013, 0.009, 0.006 and 0.004 min^-1 for HA concentrations of 0, 5, 10, 15 and 20 mg/L, respectively. The relationship between HA dosage and k values can be described as a linear model.
