Adsorption of Humic Substances by Using Coconut Copra

TCE adsorption by GAC preloaded with humic substances

ranular activated carbon (GAC) adsorption has been identified by the Safe Drinking Water Act amendments of 1986 as the best available technology for removing synthetic organic contaminants (SOCs) from drinking water supplies.1 GAC is particularly suited for treating water because it effectively removes a wide range of organic compounds and can protect water supplies from such transient occurren...

Cation binding by humic substances

Humic substances are highly abundant organic compounds formed in soils and sediments by the decay of dead plants, microbes and animals. This book focuses on the important binding properties of these compounds that regulate the chemical reactivity and bioavailability of hydrogen andmetal ions in the natural environment. Topics covered include the physico-chemical properties of humic matter and i...

Removal of Humic Substances from Water Using Solar Irradiation and Granular Activated Carbon Adsorption

Adsorption Process for Wastewater Treatment by using Coconut Shell

Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. The adsorption f...

Phenanthrene adsorption by soils treated with humic substances under different pH and temperature conditions.

The mobility of phenanthrene (PHE) in soils depends on its sorption and is influenced by either the existing soil humus or exogenous humic substances. Exogenous humic acids (HAs) were added to soil to enhance the amount of soil organic carbon (SOC) by 2.5, 5.0, and 10.0 g kg(-1). PHE desorption of the treated soils was determined at two pH levels (3.0 and 6.0) and temperatures (15 and 25 degree...
