“…Rosin is obtained through the distillation process of pine resin. The most important uses of rosin are: manufacture of adhesives, printing ink, insulating materials for the electronics industry, synthetic rubber, chewing gum, soaps and detergents due to its mixture between abietic acid and isopimaric acid [ 6 , 9 , 10 , 11 , 12 , 13 ]. Rosin remains as a non-volatile fraction after distillation for turpentine separation.…”

Rosins and turpentines present in pine resins have been widely used both industrially (coatings, electronics and paint) and pharmaceuticals (ointments). Among the main components of these matrices is abietic acid. This study focuses on the characterization and evaluation of the quality of rosins and turpentines in addition to the quantification of abietic acid in rosins. Rosin and spirit of turpentine were obtained separately through the distillation method from P patula and P. oocarpa resin, species grown in the Department of Cauca-Colombia. Resin-tapping was made using the traditional method (cup and gutter). Quality indicators were determined according to ASTM standards. Solubility tests and identification of functional groups were performed on the obtained rosin by ultraviolet-visible spectroscopy (UV-Vis), infrared (IR) and nuclear magnetic resonance ( 1 H-NMR). The abietic acid present in the rosins was determined by high performance liquid chromatography (HPLC). According to their high acid value and low percentage of unsaponifiable matter, the extracted rosins are considered of medium-high quality. Quantification of abietic acid by HPLC showed 14.85 ± 0.24% and 16.09 ± 0.11% for P. patula and P. oocarpa rosin respectively.

“…Así, deben de llevarse a cabo operaciones de desorción con el fin de separar los contaminantes adsorbidos al biocarbón y poder reutilizar éste nuevamente en el tratamiento de aguas contaminadas hasta agotar su capacidad regenerativa. En este sentido, destaca el estudio llevado a cabo por [50], en el cual se empleó un solvente como el metanol (CH3OH) para separar los contaminantes emergentes IBU y ácido salicílico (AS). Tras utilizar metanol, se logró recuperar el 88% y el 93% de IBU y AS, respectivamente [50].…”

El biocarbón es el producto procedente de la descomposición de biomasa, cuyas características fisicoquímicas están asociadas al origen de ésta y al método de combustión utilizado. Entre estas propiedades, destacan el área superficial, la formación de macro y microporos, y la presencia de grupos funcionales. Debido a estas características, el biocarbón se convierte en un material alternativo con alta capacidad de adsorción de compuestos tóxicos presentes en las aguas residuales contaminadas. Este trabajo brinda información sobre los mecanismos de generación del biocarbón y cómo éstos interfieren en sus características fisicoquímicas. Asimismo, se describen los parámetros que intervienen en los procesos de remoción de contaminantes y se mencionan los tratamientos bajo los cuales el biocarbón se puede ver sometido para mejorar su capacidad de adsorción. Finalmente, se indican los posibles usos o la adecuada disposición final que debe tener el biocarbón en aras de contribuir a la estrategia de economía circular.

“…There are many preparation methods of porous ZnO, such as solid phase, gas phase and liquid phase, among which liquid phase is the most commonly used synthesis method. Liquid phase method generally includes sol-gel method [13], direct precipitation method [14], microemulsion method [15] and hydrothermal synthesis method [16]. Compared with other preparation methods, the hydrothermal synthesis method is simple and the prepared ZnO has the good crystallinity, easy grain dispersion, small particle size and uniform distribution.…”

ZnO and cobalt doped ZnO were prepared by hydrothermal method with zinc acetate dihydrate, cobalt acetate tetrahydrate and urea as raw materials and sodium citrate as surface modifier. Congo red (CR) was used as the pollutant model for adsorption and photo-catalytic experiments. Under the same conditions, the adsorption effect of cobalt doped ZnO with different urea content on CR was investigated, and the optimum urea content was determined. Under the same conditions, the adsorption and photocatalytic properties of cobalt doped ZnO prepared with the best urea content at different annealing temperatures were studied. According to the analysis of experimental data, the adsorption effect of Co doped ZnO with urea content of 8mmol and annealing temperature of 300℃ is the best, and the photocatalytic effect is also the best under the same conditions.
