This paper is the result of our collaboration with the group of friends Bozo D. Dalmacija and Srdjan D. Roncevic at the Department of Chemistry, Biochemistry and Environmental Protection, Faculty of Sciences, University of Novi Sad, Serbia. The collaboration was started a few years ago in the framework of the IPA HU-SRB project "MATCROSS". Although the project itself is long finished by now, we enjoy a mutually beneficial cooperation where we synthesize nanomaterials az Szeged and our friends test them for various environmental chemistry tasks. The material of choice for this paper was a literally "hot" topic: zero valent iron nano particles are extremely reactive, which is exactly the reason why they can be utilized so successfully in the on-site degradation of too stable industrial organic wastes.
Thank you and let's keep up the good work guys!
