Enzyme Catalysis
(1) Enzymes are complex nitrogenous substances these are actually protein molecules of higher molecular mass. (2) Enzymes catalyse numerous reactions, especially those connected with natural processes. (3) Numerous reactions occur in the bodies…
Acid–base catalysis
Acid–base catalysis, acceleration of a chemical reaction by the addition of an acid or a base, the acid or base itself not being consumed in the reaction. The catalytic reaction may be acid-specific (acid catalysis), as…
Catalytic Promoters
Substances which themselves are not catalysts, but when mixed in small quantities with the catalysts increase their efficiency are called as promoters or activators. (i) For example, in Haber’s process for the synthesis of…
AUTOCATALYTIC REACTIONS
A chemical reaction is called autocatalytic if at least one of the reaction products acts as a catalyst in the same or in one of the coupled reactions. Reactions of…
Catalysis
Most reactions that occur in nature or synthetically require a lot of time for completion. In order to speed up the reaction, a substance called the catalyst has to be…
Adsorption Isotherm
Now that you know what adsorption is, how do we measure or study it? The process of adsorption is usually plotted and studied using a graph. This is called adsorption…
How Do Reverse Osmosis Filter Systems Work What Do They Do?
If you’re looking for a water filter that will provide outstanding drinking water for your home or business, Reverse Osmosis (RO) filtration is one of the most popular and best water…
Zeolite process for water softening
What is zeoliteZeolite is micro-porous mineral which is used as catalyst in many industrial purposes such as water purification and air purification. The zeolites are hydrated aluminosilicates and general composition…
Ion Exchange
Figure 1: Typical ion exchange configuration. Included Processes: Greensand Filtration Ion exchange (IX) processes are reversible chemical reactions for removing dissolved ions from solution and replacing them with other similarly charged…
External Water Treatment
“External water treatment, as the term is applied to water prepared for use as boiler feed water, usually refers to the chemical and mechanical treatment of the water source.”1Boiler feed water is…
