Anticorrosive protection system based on nanocomposites
Environmental Engineering and Management Journal › Vol. 8 › Nr. 4 Abstract
Corrosion control, using inhibitors like, polymerisable porphyrins and multifunctional nanocomposites, is extremely useful in many environments. Phosphogypsum is a waste product resulted from the process of obtaining the phosphoric acid and it can be also used as corrosion inhibitor; in a mixture with other coating materials.
Two types of modified porphyrin: Na4TFP Ac - dissolved in KOH and H2SO4 and H2TPP - dissolved in benzonitrile, were tested. The structure characterization of pho...

A NEW METHOD FOR THE EVALUATION OF RADON CONCENTRATION WITHIN A DEDICATED VESSEL
Environmental Engineering and Management Journal › Vol. 13 › Nr. 7 AbstractEvaluation of radon concentration is a very difficult task and a very important issue, in relation to the protection of human health.This is especially the case when there is an increase in concentration of radon on a deterministic basis, as is the case of nearbyphosphogypsum residues or geological characteristics. Radon gaseous that can be found in the environment occurs mainly fromnatural radioactive decay chains. The gamma ray spectroscopy is a powerful tool in order to monitor the en...

EFFECT OF FLY ASH ON CROP YIELD AND PHYSICO-CHEMICAL, MICROBIAL AND ENZYME ACTIVITIES OF SODIC SOILS
Environmental Engineering and Management Journal › Vol. 15 › Nr. 11 Safe utilization of fly ash (FA) and reclamation of sodic soils are important environmental problems. In this study a field experiment was carried out with Vigna radiata L. crop using fly ash (FA) and phosphogypsum (PGY) as amendments in sodic soil during 2011 at Lucknow, Uttar Pradesh, India. V. radiata L. was sown in sodic soil amended with press mud (10 t ha-1) considered as control. Besides, 10 and 20 t ha-1 doses of FA and PGY were considered as other four treatments, respectively. The grow... Autori: Kripal Singh ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=27180
HEAVY METALS AND GAMMA RADIOACTIVITY BIOACCUMULATIONIN Artemisia absinthium L. GROWN ON A WASTE DUMP
Environmental Engineering and Management Journal › Vol. 16 › Nr. 4 In the current context of industrialization, chemical and radioactive pollution is a concern for environmental protection and
interference with human health. Care for environmental protection also includes vegetation that grows spontaneously in
potentially contaminated places, thus avoiding illness among the population if consumed. The study area is located at 4.5km SSE from downtown Bacău City, Romania and is the result of the manufacture of H3PO4 through the wet method. In this study, t...
