Samples of motor oil and creosote are subjected to three-dimensional fluorescence spectroscopy document the shifting excitation/emission maxima as solutions undergo serial dilutions. Effects such self-quenching individual polycyclic aromatic hydrocarbons (PAHs) energy transfer between PAHs combine produce large red-shifts in resulting emission spectra. The concentration-imposed complications also demonstrated for several synthetic ternary PAH mixtures a diesel residue mimic.
3-D topographic surfaces ("topos") can be generated to visualize how pH behaves during titration and dilution procedures. The are constructed by plotting computed values above a composition grid with volume of base added in one direction overall system on the other. What emerge surface features that correspond behavior aqueous solutions. Equivalence point breaks become cliffs pinch out dilution. Buffer effects plateaus. Dilution alone generates 45° ramps. Limitations Henderson–Hasselbalch...
Abstract The city of Missoula is located in a high mountain valley (elevation 3200 ft) western Montana and contains one the largest populations entire Rocky Mountain Region completely enclosed by mountains. During 2000/2001 Valley Sampling Program, ambient levels 61 semivolatile organic compounds (SVOCs) 54 volatile (VOCs) were originally quantified before refining analytical program to 28 most prominent SVOCs VOCs found airshed. These measured over 24-hr periods at two locations throughout...
Complexation TOPOS is a free software package to generate 3-D topographic surfaces ("topos") for metal–ligand complexometric titrations in aqueous media. It constructs by plotting computed equilibrium parameters above composition grid with "volume of ligand added" as the x-axis and overall system dilution y-axis. The sample systems this paper are restricted EDTA ligand. Other chelating ligands that form exclusively 1:1 complexes could also be modeled software. show quality equivalence point...
BufCap TOPOS is free software that generates 3-D topographical surfaces ("topos") for acid–base equilibrium studies. It portrays pH and buffer capacity behavior during titration dilution procedures. Topo are created by plotting computed values above a composition grid with volume of NaOH as the x axis overall system y axis. What emerge surface features correspond to behaviors in aqueous solutions. pH, log capacity, linear capacity. Equivalence point breaks become cliffs logarithmic canyons...
In this paper we identify an error in the literature pertaining to interpretation of nonintegral slopes Schubert plots for metal-humate and metal-fulvate systems, derive equations that correctly describe behavior these systems.
Two characteristics of batteries, their delivery nearly constant voltage and rapid failure, are explained through a visual examination the Nernst equation. Galvanic cells described in detail: (1) wet cell involving iron copper salts (2) mercury oxide dry cell. A complete description requires three-dimensional surface because potential is function two variables: activities both oxidized reduced forms each redox couple. Dry potentials, which utilize solid or pure liquid species, functions only...
Abstract A fine particulate matter (PM2.5) sampling program was conducted in Missoula, MT, to investigate both the particle and vapor phases of PM2.5-associated polycyclic aromatic hydrocarbons (PAHs) found a northern Rocky Mountain urban airshed. Twenty-four-hour samples were collected during cold winter months January through April 2002, when many more volatile organic components PM2.5 expected be condensed form. To meet analytical detection limits, each 12 individual sample days...
A yearlong sampling program for PM2.5and semivolatile organic compounds (SVOCs) was conducted in 2000/2001 Missoula, Montana by The University of Montana, Department Chemistry. One aspect this to investigate the SVOC fraction Missoula Valley PM2.5by evaluating a Federal Reference Method (FRM) PM2.5sampler modified with Polyurethane Foam (PUF) sorbent (PM2.5PUF). In addition, method comparison made between SVOCs using PM2.5PUF sampler and high-volume PUF (Hi-vol PUF) following EPA protocol....
Species TOPOS is a free software package for generating three-dimensional (3-D) topographic surfaces ("topos") acid–base equilibrium studies. This upgrade adds 3-D species distribution topos to earlier that showed pH and buffer capacity behavior during titration dilution procedures. It constructs by plotting computed α values above composition grid with volume of NaOH added as the x axis overall system y axis. The systematic shift from protonated deprotonated forms clearly visualized on...
Diluting a system with metal complexes can sometimes cause free ions to increase in concentration. This paper describes “metal ion anti-buffering”, situation which concentrations rapidly as dilution drives dissociation. It only occurs under excess ligand conditions when solution is dominated by higher stoichiometry complexes. The Law of Mass Action used provide mathematical justification for the phenomenon. A Cu2+-ethylenediamine mixture exhibits this phenomenon ethylenediamine (en) present....
