​NEWRI-R3C Sharing Session​ (​NRSS) Season 2​​

Published on: 03-Jan-2017


  1. To improve skills on public speaking, questions handling and preparation of presentation aids (contents/formats/illustrations) for all R3Cians.
  2. To update research progress, increase awareness of R3Cians as ambassadors representing NTU-NEWRI-R3C and promote bonding as a cohesive research group.​
  3. ​To promote interdisciplinary learning, discover opportunity in the interfaces between disciplines/projects and encourage cooperation in research proposals + TD/patents development.

Session 8: 21 April 2017, 9.30am to 10.30am, ​NEWRI Meeting Room 1​​, CTO-06-08

Speaker 1: Dr Zhang Yuanyuan (Research Fellow)

Title: Heavy Metals Speciation in Sediment and Their Leaching Behaviours under Different Water Condition


This presentation will show the study on the distribution of heavy metals in dredged sediment and their mobility under different water conditions. In detail, BCR-sequential extraction procedures were conducted to understand the speciation of heavy metals in sediment. A chelating agent (i.e., EDTA) was used to investigate the mobility of heavy metals. The pH influences on the mobility were also discussed in this study. This study could provide qualitative and quantitative information on the speciation of heavy metals and their bioavailability, and facilitate further research on exposure risk assessment as dredged sediment is reused in engineering applications.

Session 7: 31 March 2017, 11am to 12pm, ​NEWRI Meeting Room 2​​, CTO-06-08

Title: Adsorption Based Separation of R134a, R125 and R143a Using 13X and Surface Modified 5A Zeolite


This presentation covers the adsorption based separation of industrially important fluorocarbon blends using commercial 13X zeolite and surface modified 5A zeolite. Commercial 13X zeolite was successfully utilized to separate R134a from a mixture of R134a, R143a and R125. The pore size of commercial 5A zeolite was modified using chemical liquid deposition(CLD) of TEOS. The modified 5A zeolite selectively adsorbed R125 and excluded R143a based on their different molecular sizes. This proposed method for the separation of above mentioned fluorocarbon blend can be easily scaled up for the direct industrial applications. ​
