Zero electric point and isoelectric point
Zero Potential Point and Equilibrium Point
In electrochemical systems, the zero potential point is used to refer to the point of electrochemical equilibrium at which the potential of an aqueous solution is the same for all components. It is a point on the electrochemical potential of a reaction w......
Sodium sulfide leaching
Sodium sulfide leaching
Sodium sulfide leaching is considered to be a kind of leaching method mainly applicable to oxidized gold-bearing ores. The advantages of using sodium sulfide for gold leaching are that the reaction rate is rapid, the corrosion of equipment is reduced, and the formation of g......
Amine collector
Amine Receptor-Based Catch Reagents
Amine receptor-based catch reagents, also known as “affinity reagents” or “binding reagents”, are used in research and industrial processes to specifically and selectively bind particular target amines. These reagents have been developed to target a wide ra......
Karst area survey
Karst landscapes are geographically widespread and are developed predominantly on a variety of carbonate rocks, although areas of limestones, gypsum and hydrogenic rocks are also affected in certain regions. The term ‘karst’ is derived from the Karst topography of the limestone region of Sloveni......
hydrogen sulfide poisoning
Introduction
Hydrogen sulfide (h2s) is a naturally occurring chemical compound found primarily in petroleum, petroleum pollution, and large deposits of decaying organic matter. It can also be created by industrial activity, such as welding and smelting. Hydrogen sulfide is a colorless, very toxic......
chemical precipitant
Chemical Precipitant
Chemical precipitants are compounds that, when mixed with a solution, cause the solution to become cloudy or otherwise change its physical state. Typically, the change is due to the formation of a solid-state precipitate that may be visible to the naked eye. Chemical precipita......
Hydrochloric acid pickling wastewater treatment design
Design of Sulfuric Acid Pickling Waste Solution Treatment
Abstract
The nickel industry is now a major consumer of sulfuric acid. The industrial scale production of sulfuric acid generates a large amount of spent pickling liquid. It is necessary to treat this kind of liquid before returning it to......
Shaking bag desulfurization
The Sulfur Removal Method with Rock Bags
Rock bag desulfurization (RBD), also known as scrubber desulfurization, is a cost-effective method to remove sulfur emissions. The method can be applied to dozens and hundreds of smokestacks, and is widely used in many countries. Rock bag desulfurization s......
Gas separation equipment
Gas Separation Equipment
Gas separation equipment is an important tool used in a variety of industries to separate gases into components with different physical, chemical and/or thermal characteristics. This type of equipment is commonly used in the oil and gas, chemical, process and power indust......
