The ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometer) is a rapid technique which can sequentially analyze about 70 chemical elements at trace, minor and major concentration levels. ICP-OES is very effective for environmental analysis because it can measure a variety of samples. Calibration range is from ppb to % grade. ICP-OES is very important technique for determining trace earth elements. Each element has specific energy levels and wavelengths which can make emissions on these energy levels. Measuring wavelength and emission intensity, elements and their quantity in one sample can be determined.

In our institute a Perkin Elmer Optima 2000 DV ICP-OES equipment is installed. The main components of the ICP-OES are listed as below:

  •   RF Generator
  •   Peristaltic pump
  •   Nebulizer
  •   Spray chamber
  •   Injector
  •   Torch
  •   Optic spectrometer

 

 

In Chemical Process Laboratory, basic chemical process related to nuclear fuel technology and waste management are conducted. In this context, recovery, concentration and purification of uranium and thorium from ore or several sources, preparation and characterization of thorium and uranium compounds are carried out. Moreover, synthesis of various types of adsorbent/ion exchangers and separation of lanthanides(La, Ce), actinides(Th, U) and fission products(Cs, Sr) using naturally occuring isotopes are investigated. 

 


  

 

In Thermal Treatment Laboratory, synthesis, separation, drying and digestion processes are carried out with systems and instruments using heat. The laboratory consists of Microwave Digestion System, Thermostatically Controlled Shaker, Vacuum Oven, Centrifuge and Tube Furnace.

  • Tube furnace

 



In the Radioanalytical chemistry laboratory, the concentration and recovery of certain radionuclides from dilute aqueous solutions using various separation techniques (solvent extraction, precipitation, ion exchange, impregnation, sorption, etc.) are realized. For this purpose, natural, biological, nano sized materials and nano composite materials are synthesized / prepared as sorbent for removal of several radionuclides from aqueous solutions, sorption behaviour of radionuclides and thermodynamic properties are investigated. The determination of natural radionuclides in the environmental samples (terrestrial and aquatic) using Radioanalytical techniques; gross alpha and total radium isotopes activities concentrations in the water samples are performed.

The available systems in the laboratory:

  •  Thermostat shaker water bath

In the Instrumental analysis laboratory, qualitative and quantitative element analysis is performed with UV-Vis spectrophotometer. The concentration of gross alpha activity is determined in terrestrial and aquatic samples by alpha scintillation detector. The activity concentration of natural radionuclides (U, Th and K) in sediment, soil, rock and biological samples are measured using gamma spectrometric method. In addition, radiation dose rate measurements are carried out in field studies.

Micromeritics’ ASAP 2020 Accelerated Surface Area and Porosimetry analyzer uses the gas sorption technique to generate high-quality data for research and quality control applications.

The ASAP 2020 is used to characterize the active and support surfaces of catalysts, to determine the high surface areas of adsorbents, microporosity and hydrogen storage capacity of various nano materials. Materials with low surface areas such as powdered metals, glass fibers, and natural organic materials can also be analyzed.

 

Fourier Transform Infrared (FTIR) spectroscopy, is a technique that based on the measurement of the excitation of molecules to the vibration and rotation levels by the absorption of IR light (wavelength of 0,78 – 1000 µm or wave number of 12800 – 10 cm-1). Functional groups in the structure of the organic compounds of solid, liquid gaseous or solution form, status of the bonds in the structure, bonding spots and the aromaticity or the aliphaticity of the structure can be determined by the characterization of molecular bonds. This spectroscopic technique has advantages as obtaining rapid, accurate and effective results,  without being non-destructive and without any need to detailed sample preparation. FTIR spectra can provide qualitative and quantitative data about chemical concentration, composition, conformation and functional groups.

Attenuated Total Reflectance (ATR) technique, makes possible to analyze materials that has a high absorptivity independent of less effort and sample thickness by providing a decrease in wavelength of absorption bands. By ATR technique, diffraction of the beam is measured instead of absorption and reflection of the beam (transmission method) by the sample. It is also very effective for the analyses of coating ingredients such as polymers, foam, textile and dye.

PERKIN ELMER SPECTRUM TWO model FTIR-ATR instrument is installed in our institute.
