2. Graphite oxide production from vein graphite as a value addition

 

Graphene and graphene oxides are highly valuable materials (>1000 times) which can be synthesized from Sri Lankan natural graphite as a value addition. Graphene oxide (GO) was synthesized from local graphite as a value addition to local graphite resource.

Technology Transfer: The technology was transferred to the Industry

 

Patents: ITI holds 02 Sri Lanka Patents

 

 

3. Graphene production from vein graphite as a value addition

Considering the high demand, Graphene was synthesized using high quality Sri Lankan vein graphite as a value addition to the graphite resource for the first time in Sri Lanka.

Project output/outcomes

 

  • An efficient low cost method was developed to prepare few layer graphene from local graphite as a value addition.
  • An apparatus was constructed to prepare graphene and reduced graphene oxide on mass scale in few minutes.

 

Technologies Transfer: The technology was transferred to the industry

 

Patents: ITI holds 02 Sri Lanka Patents

 

Awards: A Gold medal for Sahasak nimayum awards 2022 was received for the apparatus constructed to prepare graphene.

 

4. Purification of graphite above 99.9% (chemical method)

 

Graphite is being exported without much value addition at low price. Highly pure graphite is several times more expensive than raw graphite. A project was initiated to purify graphite above 99.9% as a high value addition to vein graphite sources in Sri Lanka in a cost efficient and effective manner.

Technologies Transfer: The technology was transferred to the industry

Patents: : ITI holds 1 Sri Lankan patents.

Awards: : A silver medal from Sahasak nimayum awards 2022 was received for this innovation.

 

 

5. Purification of graphite (non-chemical)

Graphite is being exported without much value addition at low price. Purified graphite is several times more expensive than raw graphite. An apparatus was constructed to purify low grade graphite up to 99%

dr Iresha 5

Technology Transfer: A novel non-chemical method was developed and necessary purification plant was constructed to purity low grade graphite up to 99% carbon and know how was transferred to industry

Awards: Dasis award and a Gold medal for Sahasak nimayum awards 2022 was received for this innovation.

Patents: 02 Sri Lanka patents (filed)

 

6. Red clay based water filter for removal of Fluoride and Heavy metals

 

Chronic Kidney Disease of Unknown etiology (CKDu) has been reported to occur in several areas of Sri Lanka, mostly in the North Central and North Western provinces. Water contamination is the suspected cause for the disease. Imported filters and local filters are being distributed by various organizations. We have developed a low cost, durable, quality guaranteed water filter for removal of fluoride, arsenic and cadmium from water, most of the suspected ions for CKDu.

dr Iresha 6

 

Technologies Transferred/Commercialized:  

  • Technology of fabricating clay water filter for removal of fluoride, arsenic and cadmium was transferred to Red Cross International Organization in 2016
  • A pilot water filter system for removal of fluoride ions and water hardness was transferred to an ice cream factory in Nikawaratiya in 2015

 

Patent: ITI holds 05 Sri Lanka patents

Awards:

  • A Gold medal for Sahasak nimayum awards 2021 by Sri Lanka Inventors commission
  • Presidential awards-2017 –a merit award for Red clay filter for removal of fluoride and heavy metals
  • Presidential awards-2016-3rd place for “Red clay filter for removal of fluoride”
