  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • Adsorption performance of coconut shell activated carbon for the removal of chlorate from chlor-alkali brine stream

    Activated carbon from coconut shell was used to investigate the adsorption of chlorate from a chlor-alkali plant's brine stream. The effect of pH, flowrate, chlorate and chloride concentration on the breakthrough curves were studied in small-scale column trials. The results obtained show enhanced adsorption at low flowrates, higher chlorate concentrations, and at a pH of 10. These studies show ...

  • Kinetics and thermodynamics study of lead adsorption on to activated carbons from coconut and seed hull of the palm tree

    The kinetic and thermodynamic of the bath sorption of lead (Pb) on to activated carbon from Coconut (CA) and Seed hull of the Palm tree (GA) have been investigated. The effects of initial Pb concentration, contact time and temperature were examined. The results showed that the adsorption capacities of the activated carbons increased with the initial lead concentration. The process sorption ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...

  • Investigation of removal of N–nitrosamines and their precursors in water treatments using activated carbon nanoparticles

    N–nitrosamines have been detected in various water types. A strategy for removal of this group of compounds should be taken to reduce the health risks for humans. In this study, a fast and sensitive LC–MS/MS method was developed for quantitative analysis of nine N–nitrosamines and four precursors in a single sample. The Method Detection Limits (MDLs) in natural water ranged from ...

  • Adsorption kinetics and diffusion of Saxitoxins on granular-activated carbon: influence of pore size distribution

    Saxitoxin (STX) is the most toxic non-protein substance known. STX-producing cyanobacteria have been identified in most continents and are being detected more widely because of global warming, threatening human drinking water supplies worldwide. Removal of these components can be accomplished by adsorption on granular-activated carbon (GAC) but little is yet known about the kinetics of the ...

  • Wet hydrogen peroxide catalytic oxidation of phenol with FeAC (iron-embedded activated carbon) catalysts

    This investigation aims at exploring the catalytic oxidation activity of iron-embedded activated carbon (FeAC) and the application for the degradation of phenol in the wet hydrogen peroxide catalytic oxidation (WHPCO). FeAC catalysts were prepared by pre-impregnating iron in coconut shell with various iron loadings in the range of 27.5 to 46.5% before they were activated. The FeAC catalysts were ...

  • Companies from Chanel to Ben and Jerry’s are benefiting from the new “carbon insetting” trend

    Ten years ago, serendipity set Tristan Lecomte on his path to planting millions of trees around the world. Lecomte was CEO of the French organic and fair trade company Alter Eco, and his eco-conscious consumers were pressing him about his actions on climate change. So Lecomte calculated his company’s carbon footprint and began planting trees in partnership ...

  • Chlorate adsorption from chlor-alkali plant brine stream

    Chlorates are present in the brine stream purged from chlor-alkali plants. Tests were conducted using activated carbon from coconut shell, coal or palm kernel shell to adsorb chlorate. The results show varying levels of adsorption with reduction ranging between 1.3 g/L and 1.8 g/L. This was higher than the chlorate generation rate of that plant, recorded at 1.22 g/L, indicating that chlorate ...

  • Removal of cadmium (Cd II) from polluted seawater

    Cadmium is one of the heavy metals, highly toxic and non–degradable and, therefore, persistent. Discharges containing cadmium are controlled due to its high toxicity level and its tendency to accumulate in living organisms. The present article describes the use of coconut pith as adsorbents for removing cadmium from seawater. The method consists in preparing activated carbon from coir pith, which ...

  • Hydrocarbon evaporative emissions & control for automotives

    Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...

  • The Elimination of Ethylene in Domestic Refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Eliminating ethylene from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...
