Facing Challenges and Searching Chances at the Same Time——The Present Status of Chinese Flower Enterprise

Chen Junyu

Strategic Study of CAE 2002, Volume 4, Issue 10,   Pages 17-20

Abstract:

This report points out that the flower enterprise is a promising enterprise, growing up continuously and becoming better and better. The author then compares and analyses differences and commonalities between the Chinese flower enterprise and the world flower enterprise. Using ’99 Kunming International Horticultural Exposition as an example, the author is convinced that Chinese gardens and flowers may reach the first level in the world, but “Chinese Characteristics” ought to be strengthened significantly. At the beginning of China’s becoming a member of WTO, a very good way has been found for facing challenges and utilizing good chances——the so-called “Hua-Hui Xin Si Hua”，viz,①traditional Chinese famous flowers internationalized;②world famous flowers becoming“sinicized” and localized;③ wild flowers introduced and acclimatized;④flower production and management highly specialized and in large-scale. It is possible to reach the present level of flower development in the world in 50 years or more. Then，China will be turned from the “Mother of Gardens” to the “Kingdom of World Flowers”.

Effect of Fe loading quantity on reduction reactivity of nano zero-valent iron supported on chelating

Jialu SHI,Shengnan YI,Chao LONG,Aimin LI

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 840-849 doi: 10.1007/s11783-015-0781-2

Abstract: In this study, nanoscale zero-valent iron (NZVI) were immobilized within a chelating resin (DOW 3N). To investigate the effect of Fe loading on NZVI reactivity, three NZVI-resin composites with different Fe loading were obtained by preparing Fe(III) solution in 0, 30 and 70% (v/v) ethanol aqueous, respectively; the bromate was used as a model contaminant. TEM reveals that increasing the Fe loading resulted in much larger size and poor dispersion of nanoscale iron particles. The results indicated that the removal efficiency of bromate and the rate constant ( ) were decreased with increasing the Fe loading. For the NZVI-resin composite with lower Fe loading, the removal efficiency of bromate declined more significantly with the increase of DO concentrations. Under acidic conditions, decreasing the pH value had the most significant influence on NZVI-R3 with highest Fe loading for bromate removal; however, under alkaline conditions, the most significant influence of pH was on NZVI-R1 with lowest Fe loading. The effects of co-existing anions , and were also investigated. All of the co-existing anions showed the inhibition to bromate reduction.
