Pyrolysis of oil sludge first by thermogravimetry/mass spectroscopy (TG/MS) and then in a horizontal quartz reactor with an electrical laboratory furnace under different pyrolysis conditions was carried out. The influence heating rate from 5 to 20 °C·min-1, final temperature 400 700 °C, various interval holding stage, catalyst on the products were investigated detail. TG/MS results show that reaction starts at low about 200 maximum evolution is observed between temperatures 350−500 °C. A...
Specific surface area and charge properties such as potential, density, electrostatic field strength at surface, number are important characteristics of charged particles in soil the environment. Currently there is not a theory or method that could give combined determination for those parameters from single experiment. In this paper, an approach described employs cation exchange experiments to develop data can be interpreted using newly derived set theoretically-based equations. First we...
A quantitative description of specific ion effects is an essential and focused topic in colloidal biological science. In this work, the dynamic light scattering technique was employed to study aggregation kinetics particles various alkali solutions with a wide range concentrations. It indicated that activation energies could be used quantitatively characterize effects, which supported by results effective hydrodynamic diameters, rates critical coagulation At given concentration 25 mmol...
Hofmeister effects continue to defy all-encompassing theories, and their origin is still a matter of debate. We observed strong in Ca2+/Na+ exchange on permanently charged surface over wide range ionic strengths. They could not be attributed dispersion forces, classical induction size, or hydration effects. demonstrated that another stronger force was active the ion-surface interactions, which would create general. The strength this up 10(4) times force, comparable Coulomb force. Coulomb,...
The Hofmeister or specific ion effects are not involved in the existing exchange equilibrium theories. In this study, a new cation model considering was established. relative adsorption ability quantified through energy selectivity coefficients of ions. quantificational sequence ratio ((relative energe for i ion)/(relative j ion)) calculated from obtained: Ca > Mg ((Ca2+)/(Mg2+) = 1.407) K ((Mg2+)/K2+ 1.467) Na (K+/(Na2+) 1.646) Li ((Na2+)/(Li2+) 1.110). It provided theory description ionic...
Abstract The aggregation of variably charged nanoparticles is usually induced by the changes in internal and external conditions, such as solution temperature, pH, particle size, van der Waals force, electrostatic repulsion among particles. In order to explore effect pH on variable charge nanoparticles, this paper proposed an extended model based 3D on-lattice Cluster–Cluster Aggregation (CCA) model. successfully established relationship between sticking probability, used Smoluchowski theory...
Soil particle interactions are strongly influenced by the concentration, valence and ion species pH of bulk solution, which will also affect aggregate stability transport. In this study, we investigated clay in presence different alkali ions (Li+, Na+, K+, Cs+) at concentrations from10−5 to 10−1 mol L−1. Strong specific effects on were observed, showed order Cs+>K+>Na+>Li+. We found that it was not size, hydration, dispersion forces cation–surface but strong non-classic polarization adsorbed...
Irrigated agriculture has been in a quandary of sustaining its productivity for centuries while attempting to cope with soil and water salinity issues that continue devastate crop production. Several the research gaps associated current irrigation practices include how assess leaching requirement (LR) efficiency (LE) different soils, crops, regimes. The objective this study was test application methods on using laboratory column experiments computer model simulations. Three (continuous...
Abstract Metal–organic cages (MOCs), a novel type of porous material, have shown great potential in the adsorption and separation CO 2 gas. Zirconium‐based metal–organic (Zr‐MOCs) garnered special attention because their outstanding stability high solubility. Nevertheless, due to its powdery nature tendency for easy aggregation, application industrial field is limited. Here, drawing inspiration from water treatment, inexpensive stable ionic exchange resin D001 was employed as supporting...
Accurate estimation of the surface charge density nano/micro particles is crucial for regulating their environmental fate and bioavailability in fields science materials engineering. However, existing analytical methods accurately estimating remain significant challenges. In this study, we proposed a method through aggregation experiments using dynamic light scattering technology. The specific ion effect had on accuracy these estimations. Without considering effect, led to significantly...
The structural stability of clay minerals is an important geochemical process. However, a long-standing challenge to understand the surface reaction mechanisms for mineral structure stability. Quantum mechanical analysis indicates that strong reaction, electric-field-dependent covalent interactions between H+ and basal oxygen (O) atoms montmorillonite (MMT) surface, occurs in hydrothermal experiments. strongly depend on orbital hybridization siloxane at MMT increase with increasing acid...
