Micromolar photochemical system

micromolarThe micromolar photochemical reactor is a system that allows the controlled irradiation of small volumes containing photoactive species in both homogeneous and heterogeneous phases. Its irradiation source can be sunlight or an artificial halogen lamp and it is used to study photochemical reactions in real time, avoiding perturbations in the reaction medium and allowing external factors that might influence the reaction to be controlled..

 

Spectrophotometers

  • Fluoromax-4 Horiba Jobin Yvon Fluorometer
  • JASCO V650 UV-Vis spectrophotometer
  • Hach Lange UV-Vis spectrophotometer

 

Monochromator-coupled deuterium lamp. 

It is mainly used to study photochemical reaction mechanisms, identification of reaction intermediates and kinetics.

 

 

Reaction carousels.carrusel

Each one can host up to 12 reaction tubes with Teflon caps to work in different kinds of atmospheric conditions and temperatures. Condensation of vapour is permitted by a chilling circuit in the upper part of the system. The working temperature ranges are from room temperature up to 300ºC.They are mainly used to study catalytic reactions versus time and temperature along with varying the atmosphere.

 

UPLC Agilent Technologies series 1200

This equipment allows the analysis of substances present in aqueous and organic media with high precision and with a relatively short time analysis by reverse chromatography due to their ability to work at high pressure. This device is used for the detection of contaminants in water and allows the removal of these contaminants to be studied with the different processes studied in the CIESOL..

 

SHIMADZU GC-2010 Gas chromatographGC-2010

The gas chromatograph is equipped with a capillary column Supelco SP-2330 with a FID detector, with the possibility of sample injection split/splitless. It is mainly used to separate and identify organic substances produced in catalytic processes with organometallic compounds and using sunlight and/or heat as the energy source.

 

AB SCIEX QTRAP 5500 LC/MS/MS

5500

The QTRAP is designed to excel at metabolite identification, detection and confirmation of low-level pesticides, It also houses a high sensitive ion trap along with offering ultra-fast scan speeds and full MS3capabilities. Perform multiple reaction monitoring (MRM) scans for quantitation using this high-sensitivity triple quadrupole system.

  • Identify, characterize, and quantitate metabolites more quickly and easily.
  • Enable high-sensitivity, full-scan MS, MS/MS, and MS3with high-selectivity from true triple quadrupole precursor ion (PI) and neutral loss (NL) scans.

 

BRUKER 320MS Mass spectrometer triple quadrupole coupled to BRUKER 450GC gas chromatograph. 450

This chromatographic system complements the previously mentioned ones because it allows analysis of organic compounds of low/medium polarity. It is used especially for the determination of trace levels of contaminants such as synthetic fragrances, and pesticides, among others.

 

Ion chromatograph (Metrohm 881 Compact IC Pro). 

ciThis equipment allows the accurate analysis of anions or cations in concentrations from μg/L to g/L, with detection limits of <1 μg/L. This system is essential for the characterization of the aqueous effluents used for experimentation, since the presence of certain cations as phosphates and chlorides affects various processes of water decontamination conducted at CIESOL (Fenton and solar photo-Fenton).

 

Total organic carbon analy (TOC). toc

These analysers allow the dissolved carbon and nitrogen to be determined. In the laboratory they are used for the determination of inorganic and organic carbon and nitrogen dissolved in liquid samples of wastewater to evaluate their purification when oxidative treatments are applied.

 

Biochemical oxygen demand analyzer (BOD).  

Biological oxygen demand (BOD mg O2/L) determines the relative oxygen requirements of wastewater effluent and contaminated water for biological degradation. This measure expresses the degree of contamination due to potentially biodegradable organic matter (under aerobic conditions) of wastewater. It is used to control the improvement of biodegradability of toxic effluents treated with photocatalytic processes.

 

Chemical oxygen demand analyzer (COD). 

It is used to estimate the amount of organic matter and its oxidation state. The combination of this measure with BOD and TOC allows good overall quality characterization of a wastewater.

 

Atlas Suntest cPS+ solar simulator. suntest

This device simulates the solar spectrum, allowing laboratory scale experimentation. It is essential in pre initial scale pilot tests..

 

Pilot plants.

altura

We have four pilot plants for contaminated water treatment by photo-Fenton (usually). They operate using solar irradiation and are equipped with radiometers to record the incident radiation.

Pilot plant to evaluate the reuse of regenerated solar photocatalytic treatment water for irrigation.

 

 

Bioreactors

  • Membrane bioreactor (MBR)
  • Hollow fiber bioreactor (MBR)
  • Batch bioreactor (SBR)
  • SiClaro® 8PE Membrane bioreactor from Martin Systems AG

They are used to simulate different biological water purification processes
