Reaction Kinetics of the Hydrothermal Treatment of Lignin

Lignins derived from abundant and renewable resources are nontoxic and extremely versatile in performance, qualities that have made them increasingly important in many industrial applications. We have shown recently that liquefaction of lignin extracted from aspen wood resulted in a 90% yield of liquid. In this paper, the hydrothermal treatment of five types of lignin and biomass residues was studied: Kraft pine lignin provided by MeadWestvaco, Kraft pine lignin from Sigma-Aldrich, organosolv lignin extracted from oat hull, the residues of mixed southern hardwoods, and switchgrass after hydrolysis. The yields were found dependent on the composition or structure of the raw materials, which may result from different pretreatment processes. We propose a kinetic model to describe the hydrothermal treatment of Kraft pine lignin and compare it with another model from the literature. The kinetic parameters of the presented model were estimated, including the reaction constants, the pre-exponential factor, and the activation energy of the Arrhenius equations. Results show that the presented model is well in agreement with the experiments.

Comments on the Numerical Treatment of CPC Data

Abstract

The magnitude of the errors introduced in the calculated molecular mass averages is discussed in the case of gel permeation chromatography (CPC). It was shown, that neglecting the undetectable parts at both tails of a chromatogram where the intensity of the curve is very small, results in serious errors. For chromatograms with Gaussian shapes it was found, that if the molecular mass limits of the calculations were set at ±35 (S is the standard deviation of the curve) the numerically calculated M_n and M_m values deviated by 1 to 10% from the theoretical ones. The errors increased with increasing polydispersity and decreased as the number of data points increased. However, there was no significant difference in the results if the number of data points was greater than 20.

Influence of Water Treatment and Wastewater Treatment on the Changes in Residues of Important Elements in Drinking Water

Drinking water is the essential medium for food production, and is also needed for direct consumption; while it must be free of harmful substances, it also must have a composition that is beneficial to health. The aim of this study was to evaluate the influence of water and wastewater treatment on reducing the concentrations of zinc (Zn), nickel (Ni), iron (Fe), manganese (Mn), copper (Cu), lead (Pb), and arsenic (As) in the Western Pomerania Voivodeship in Poland. The research was carried out in 2017–2019. The analysis was performed with inductively coupled plasma atomic emission spectrophotometry (ICP-AES). The concentrations of trace elements in drinking water were below maximum acceptable concentrations (MACs). Reductions in the most dangerous elements during water treatment fluctuated from 48.5% (As) to 97% (Pb). Wastewater treatment reduced the concentrations of analyzed elements by a range of 28.6 to 60.8%, and the most toxic elements (Pb and As) by over 50%. Trace element concentrations in treated wastewater were below MAC values, and ranged from 1.15% (Pb) to 6.23% (As) of MACs for toxic elements. The concentrations of both essential elements (Zn, Ni, Fe, Mn, Cu) and toxic elements (Pb, As) in drinking water were below the MACs. Water treatment had a significant (p < 0.05) effect on decreasing trace element concentrations.

Parameters in the Pariser-Parr-Pople SCF MO Treatment

The variation of appointed parameter values in the Pariser-Parr-Pople SCF MO treatment is studied rigorously using aniline and 7-pyrone as model systems. Their effect on computation results is never ignorable. The most dominant factor is the core charge distribution, which is required to be accurate to 0.01 electron unit if truly reasenable result is to be expected. The propriety of appointing one-electron resonance integrals as empirical parameters in studying electronic transition energies is verified. Relative polarization Q of parameters and relative polarizability κ of interested physical observables are defined and are utilized in the comparative study on the effects of the variation of parameters in the treatment. A conclusion obtained is that it is possible to change energy factors of the system while keeping its structural factors unchanged' through the simultaneous variation of the valence-state ionization potential and the one-center repulsion integral of any atom in the system.     

Polysaccharide-Based Drug Delivery Systems for the Treatment of Periodontitis

Periodontal diseases are worldwide health problems that negatively affect the lifestyle of many people. The long-term effect of the classical treatments, including the mechanical removal of bacterial plaque, is not effective enough, causing the scientific world to find other alternatives. Polymer–drug systems, which have different forms of presentation, chosen depending on the nature of the disease, the mode of administration, the type of polymer used, etc., have become very promising. Hydrogels, for example (in the form of films, micro-/nanoparticles, implants, inserts, etc.), contain the drug included, encapsulated, or adsorbed on the surface. Biologically active compounds can also be associated directly with the polymer chains by covalent or ionic binding (polymer–drug conjugates). Not just any polymer can be used as a support for drug combination due to the constraints imposed by the fact that the system works inside the body. Biopolymers, especially polysaccharides and their derivatives and to a lesser extent proteins, are preferred for this purpose. This paper aims to review in detail the biopolymer–drug systems that have emerged in the last decade as alternatives to the classical treatment of periodontal disease.
