Abstract:
Graduate and post graduate students find much more difficulty during the concept of the balancing redox chemical equation in acidic or basic medium. Teachers are well aware of the importance of the balancing redox chemical equation in both medium and also teaching difficulty associated with it. In an attempt to improving the understanding of the balancing the redox chemical equation with reduced difficulty, a mathematical approach that provides easier understanding has been developed and successfully employed in graduate and post graduate students. In this study, relation between an oxidising

Abstract:
Abstract In this experiment, three kinds of hydrous manganese dioxide (HMO) with different Zeta potentials were synthesized, and combined with KMnO4 for deep removal of Pb2+, Cd2+ and Ni2+. The competitive adsorption of three heavy metal ions was also investigated. The results indicated that the stronger the acidity, the higher the Zeta potential (-54.3) of the synthesized HMO. After regenerating HMO with acidic KMnO4 as eluent, the removal rates of Pb2+, Cd2+ and Ni2+ could still reach 79.25%, 80.13% and 60.43% after five cycles of adsorption. The promoting mechanism of KMnO4's effect on HMO

Abstract:
Background: A number of theoretical and experimental approaches have been signalizing towards a induction of some solvent structural order or dynamical behavior, whenever a High Dilution (HD) is prepared. These works have been performed using different spectroscopic techniques, calorimetric studies, electrical and optical measurements, among others, which results are interpreted under many different approaches. The understanding of the physicochemical nature of HDs is still far from to be clarified, despite the evidences on their biological activity. Assuming that physicochemical changes induc

Abstract:
Ethylene is a plant growth regulator (PGR) that mainly influences on growth and development of plant and their agricultural productivity. Ethylene producing from plant tissue is a physiological indicator which refers to the maturity, senescence, or stress of plants. Therefore, a monitoring level of ethylene in plant tissue is necessary for research and commercial processes. Current method measuring gaseous ethylene is costly and take a long time. This research established a new method to quantify ethylene gas in water immersed plant by using an oxidation reaction between oxidizing agent (KMnO4

Abstract Quality of water used for injection is a very essential factor in preventing/minimizing formation damage potential due to scale precipitation. Various components in produced water such as H2S, suspended solids, bacteria and other metal ions such as iron are the primary cause of permeability impairment. Injected water should be compatible with both rock and formation fluids, thus the need to find chemical solutions to minimize the impact of injection water on formation rock arises.
