degradation of acrylic water base color from synthetic wastewater by the fenton process was performed. experiments were conducted on the sample containing 100 and 400 mg/l of acrylic water base color. the study was performed for searching optimum values of feso4 and h2o2 concentration, ph and temperature. the h2o2 requirement seems to be related to initial cod of the sample. feso4/ h2o2 ratios ...

Anaerobic microbial reductive dechlorination of PCBs is important because it removes the chlorine substituents that block aerobic metabolism and it reduces PCB toxicity. Although this process occurs widely in nature, its extent is often limited to dechlorination of some of the chlorines in the meta positions of biphenyl. In this report we demonstrate the ability to achieve nearly complete meta ...

The Dendrobium orchid is one type with special features and many variations. This study aims to determine the administration of various concentrations ferrous sulfate (FeSO4) Thiamin sp explants on Murashige And Skoog media. design used in this was a Factorial Completely Randomized Design (CRD) consisting 2 treatment levels (F = FeSO4 T Thiamin) three replications. Namely: F0 (Without FeSO4), F...

OBJECTIVES To compare the effects of wheat flours fortified with NaFeEDTA, FeSO4 and elemental iron (electrolytic iron), in improving iron status in anemic students. METHODS Four hundreds anemic students (11 to 18 years old) were divided into four groups and given wheat flour fortified with different iron fortificants at different concentrations: control group (no added iron); NaFeEDTA group ...

In this study, effective and easily accessible cheap catalysts that assist converting heavy oil residue to lighter products with high yield are investigated. Hydrocracking experiments were carried out in a 10 ml stainless steel bomb-type reactor up down stirrer at 200 times of reciprocation per minute. The catalyst mixture provided the minimum coke was FeSO4.H2O, binary mixtures FeSO4.H2O metal...

Alterations in the gut microbiota have been recently linked to oral iron. We conducted two feeding studies including an initial diet-induced iron-depletion period followed by supplementation with nanoparticulate tartrate-modified ferrihydrite (Nano Fe(III): considered bioavailable to host but not bacteria) or soluble ferrous sulfate (FeSO4: considered bioavailable to both host and bacteria). We...

Canine lingual arteries are innervated by calcitonin gene-related peptide (CGRP)-containing vasodilator nerves. Although the vascular system might be considered as the first target of oxygen-derived free radicals in some of the pathophysiological conditions, the effect of oxygen-derived free radicals on neurotransmission in CGRP nerves remains unknown. We, therefore, investigated the role of ox...

Chemiluminescence of luminol in a cell-free system was used to investigate the mechanism of alloxan-dependent free-radical generation. In the presence of alloxan and reduced glutathione (GSH), luminescence was greatly stimulated by FeSO4. Replacing GSH by oxidized glutathione or NAD(P)(H), or replacing FeSO4 by CUS04, ZnSO4 or FeCl3, did not yield chemiluminescence. The chemiluminescence of a m...

Telfairia occidentalis is a vegetable food crop that is indigenous to West Africa. The leaves and seeds are the edible parts of the plant and are used in everyday meals by incorporation into soups and stews. Previous studies have attributed improved haematological indices to the vegetable and have advocated the use of T. occidentalis in the treatment of anemia. This study investigates the ameli...
