In this study, activated carbon was produced from goat dropping with H 2SO 4 as activating agent. The produced activated carbon (GDAC) was characterized to determine its physico-chemical properties.
Legislature and Pesticides Use in Nigeria Nigerian farmers depend largely on agrochemicals such as fertilizers and pesticides for the control of many insect pests, weeds, and diseases. It was reported that about 125,000–130,000 metric tons of pesticides are
Gold Leaching carbon in leach process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as well. Gold Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.
In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two
On the other hand, as people age, they have less acid in the stomach and thus a calcium carbonate tablet may pass through the stomach without dissolving. That, in turn, may lead to constipation. However, if the calcium carbonate is taken in an effervescent formulation, the calcium dissolves in water and is readily available for the body to absorb without the risk of excessive gas in the
In this study, adsorption of Congo red dye onto activated carbon prepared from Jujube (Ziziphus Mauritiania) seeds with phosphoric acid as the activating agent was investigated. Batch adsorption studies were carried out to study the influence of contact time
Non-acidic or weakly acidic fracturing fluids are not detrimental from the aspect of dissolving and reprecipitating iron compounds. However, fracturing fluids usually contain a significant cancentration of dissolved and entrained oxygen which makes the fluid incompatible with formation water that contains ferrous ions in solution.
The screening of several products allowed identifying the chelating agent with the highest activity dissolving calcium carbonate and calcium and barium sulfate scales in a single treatment. Corrosion and sensitivity tests were carried out for the metallic and nonmetallic ESP components.
It is also used as a solvent due to a strong dissolving agent of synthetic and natural resins such as polyvinylchloride & vinylidene chloride copolymers. Increasing use of artificial leather in various appliions such as clothing, footwear, upholstery, and fabrics is set to remain a key driving factor for market growth over the forecast period.
which is also used as the solvent for dissolving the hydrophobic drug. The mixture of polymer and drug solution is then emulsified in an aqueous solution containing a surfactant or emulsifying agent to form an oil in water (o/w) emulsion. After the formation of

Carbon dioxide was the first gas to be described as a discrete substance. In about 1640, the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original …

Stered literature is harnessed to critically review the possible sources, chemistry, potential biohazards and best available remedial strategies for a nuer of heavy metals (lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel) commonly found in contaminated soils. The principles, advantages and disadvantages of immobilization, soil washing and phytoremediation techniques
Non-cyanide gold leaching agent also can be called Non-cyanide gold dressing agent or Non-cyanide gold dissolving agent is mainly applicable to heap leaching tank leaching and carbon paste agitation leaching processes of fine grind gold and silver ore - an
