adsorption‚ coagulation‚oxidation and precipitation were commonly used to treat dyes in wastewater effluent. Among these treatments‚ advanced oxidation processes (AOPs) had been widely investigated by researchers around the world and it considered as a promising treatment method to destroy these organic pollutions in wastewater. One of the AOPs so called wet air

Redox stands for reduction-oxidation‚ and are electrochemical processes involving electron transfer to or from a molecule or ion changing its oxidation state. This reaction can occur through the application of an external voltage or through the release of chemical energy. Oxidation and reduction Oxidation and reduction describe the change of oxidation state that takes place in the atoms‚ ions or molecules involved in an electrochemical reaction. Formally‚ oxidation state is the hypothetical

Several reactions such as Bromination‚ oxidation‚ and the addition of sulfuric acid were done to understand the chemical properties as well as the possible products that may form by each of the classification of hydrocarbons. Preparation of acetylene was also done in this experiment. The properties of the formed acetylene such as the reaction of the acetylene as it undergo Ammoniacal silver nitrate test‚ Bromination and oxidation. The reagents that were used to perform this experiment

classify chemical reactions in various ways. Often a major classification is based on whether or not the reaction involves oxidation-reduction. A reaction may be classified asredox in which oxidation and reduction occur or nonredox in which there is no oxidation and reduction occurring. Redox Reactions A redox reaction can be recognized by observing whether or not the oxidation numbers of any of the elements change during the

Lanthanides and Actinides The lanthanides and the actinides make up the f block of the periodic table. The lanthanides are the elements produced as the 4f sub level is filled with electrons and the actinides are formed while filling the 5f sub level Some significant similarities and differences between lanthanides and actinides are observed. The two rows that are generally placed underneath the main periodic table are called the lanthanides series and the actinides series. These two rows are produced

An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons. Oxidation reactions can produce free radicals. These radicals can start chain reactions. When the chain reaction occurs in a cell‚ it can cause damage or death to the cell. Antioxidants terminate these chain reactions by removing free radical intermediates‚ and inhibit the oxidation reactions‚ hence prevent the damage caused by oxidation to cells. Therefore‚ if we have insufficient
