Adsorption of aqueous copper on peanut hulls 2014 3587 A method was established for measuring the adsorption of Cu(II) from aqueous solution to unmodified and modified peanut hulls at constant temperature and pH. Modification of the hulls was performed by oxidation with alkaline hydrogen peroxide. During...
Quantitative analysis of the binding strength and adsorption capacity of zinc oxide nanoparticles onto unmodified and modified cotton fiber 2016 1214 Risk of bacterial infection is always a concern in hospitals, so it is important to nd ways tominimize this risk. One method for reducing the risk of infection is by using textiles withantimicrobial properties. Zinc oxide nanoparticles have antimicr...
Adsorption of copper (II) by peanut hulls in a fixed-bed, continuous flow column 2017 797 Heavy metal pollution is an important concern due to its adverse health and environmental effects. Biosorption is a way to remove heavy metals from aqueous systems with the use of biomaterials. There are many different types of biosorbents, such as a...
Chemical and physical properties of natural and modified ground peanut hulls 2017 1706 The chemical and physical characteristics of peanut hulls was assessed using methylene blue (MB) adsorptivity, physical analysis to assess surface area, and FT-IR spectroscopy to analyze chemical composition of the hulls. Peanut hulls are an agricult...
Biosorption of aqueous metal ions and metal ion mixtures onto ground peanut hulls 2017 763 The purpose of this research project was to investigate the adsorption of heavy metals onto unmodified and modified ground peanut hulls to determine their compatibility as a biosorbent for heavy metal containing aqueous environments. The adsorptions ...
Effects of pH on adsorption of copper(II) onto ground peanut hulls 2020 5 This study explores the influence of surface charge on the adsorption mechanism of Cu(II) onto ground peanut hulls at different pH values. Ground hulls can be separated into two types based on their density. For both types of hulls, adsorption capaci...
Oxidative reactions of peanut hulls 2020 11 This study investigates how a variety of oxidants can be used to chemically modify ground peanuthulls. Low density and high density hulls were modified using three different oxidizing environments: an alkaline peroxide oxidation system (APOS), potass...
Chemostratigraphic analyses of legacy and late Holocene, presettlement deposits, Upper Stick Elliott Creek, North Carolina 2020 4 Chemostratigraphy is a technique that defines and spatially correlates stratigraphic units usingsubtle variations in the elemental composition of the sediments. A collaborative study of UpperStick Elliott Creek within the Big Harris River basin near ...
