The hydrophobic organic acid (HPOA) fraction of the dissolved organic matter (DOM) collected in 2012 at the headwaters of the Suwannee River (SR) was interacted with a metal (Fe, Al) oxide-coated quartz sand, which was sourced from Oyster, VA (referr

Although physicochemical processes at liquid/solid boundaries are critical in several increasingly important areas of environmental science and engineering, research methods used to contact solutes and adsorbents have changed little in recent decades

We describe a unique C# computer program developed in our laboratory to efficiently manipulate data generated when a novel liquid chromatographic (LC) 'pulsed addition' technique is used to study organic ligand interactions with mineral surfaces. We

The effects of 640 kHz sonolysis and 60Co gamma-radiolysis on dissolved organic matter (DOM) were compared through UV/ vis absorption spectrometric, dissolved organic carbon concentration ([DOC]), and potentiometric titration analyses. A reverse-phas

The behaviour of phosphate and natural organic matter (NOM) in soils and aqueous media is strongly influenced by their association with surfaces of colloidal mineral oxide and oxyhydroxide particles of iron. Here we investigate the interaction of ato

Treatment of silsesquioxane 1 with 3.3 equiv of the reactive organoboranes 2 [(C6F5)2BX; X = H or Cl] provides the novel, trifunctional organoborane 3, which was characterized by spectroscopic mean...
Combined HPLC/HPSEC study of Suwannee River Fulvic Acid adsorptive fractionation on α-aluminum oxide

A novel liquid chromatographic (LC) method with repeated injections of Suwannee River Fulvic Acid (SRFA) was used to investigate its adsorptive fractionation by synthetic α-Al2O3. Eluent (i.e., non-retained) SRFA for each injection was monitored by

The photosensitizing properties of cresyl violet have been investigated by characterizing singlet and triplet excited states and the reduced and oxidized forms of the dye by picosecond and nanosecond laser flash photolysis. The dye readily forms a ch

Phosphate-modified AFM tips were prepared by the deposition of self-assembled monolayers (SAMs) of bis(11-thioundecyl) phosphate on Au-coated silicon nitride cantilevers. The properties of the PO(2)H-terminated SAMs were investigated by studying the
