A fresh solution for the lindane problem
Date:10/22/2013

te on a laboratory scale whether these iron nanoparticles can be applied and whether they have the capacity to eliminate the lindane," explained Itxaso San Romn, member of the UPV/EHU's Department of Analytical Chemistry. This requires advanced analytical techniques capable of monitoring the degradation process, which will take place in the presence of the various nanoparticles, determining the speed of the reaction and likewise detecting the possible by-products that are formed in the course of that reaction.

The process to degrade the contaminant itself was evaluated by analysing samples of water containing lindane using the technique called solid-phase extraction (SPE). That way the lindane remaining in the solution was measured over time. Likewise, the technique involving solid-phase microextraction (SPME) was used to detect the gas by-products generated during the degradation at each moment in the study by means of gas chromatography with a mass spectrometry (GC-MS) detector.

Through the techniques employed it was possible to compare and study the effectiveness of the various types of nanoparticles used to degrade the lindane and to find out the reaction speed in each case. The study showed how the lindane gradually disappeared in the presence of the nanoparticles over time (between 1 and 72 hours), revealing various reaction tendencies and speeds. "The protection of the nanoparticles increases the effectiveness of the degradation of the lindane and also prevents the agglomeration of the nanoparticles; the result is a greater reaction surface," pointed out Itxaso San Romn. However, "as the lindane concentration in water diminished over time, other less harmful by-products were seen to appear; as time passes these will probably be transformed into more innocuous compounds," she said. That way "both the coated and uncoated nanoparticles have been shown to be capable of transforming the lindane into other less harmful products," stressed San Romn
