from biomass following varied methods, among which dimethyl sulfoxide or dioxane (Björkman’s) and acetic acid (LCC-AcOH) processes are the most widely applied. The oxidation and methylation treatments of LCC materials elucidate the locations and frequency of binding sites of hemicelluloses to lign...
Fe impurities electrochemically plated onto the surface of the CaB6 crystals during the flux removal procedure could be completely removed, along with the ferromagnetism, by washing in hydrochloric acid. 15). Careful chemical analysis showed that this washing did not affect the La doping. This ...
Mango orchards in Pakistan are deficient in soil micronutrients. Multan is one of the prime regions for mango production in Pakistan; therefore, this study was conducted to evaluate the micronutrient status of mango orchards in the Multan region. Soil sa

[29]. Ground extrudates were extracted with a mixture of acetone, water and hydrochloric acid (70:29:1; v/v/v). Afterwards, the samples were centrifuged for 10 min and the resultant supernatant was collected and used for further analyses. The content of total phenols was determined with ...
Soil was extracted with an ammonium fluoride and hydrochloric acid solution at pH 2.5; then, the mixture was shaken and filtered. The extracted P in the filtrate was measured colorimetrically by forming a blue complex and assessing its intensity with a spectrophotometer. The SAP concentration was ...
[49] soaked RA with HCL, H2SO4, HNO3, and a mixed solution of hydrochloric acid and SP. It was found that this treatment improved the physical and mechanical properties of RAC significantly and could improve compressive strength by 8–18% at the age of 28 days, compared with untreated ...

A 1 g fruit sample was transferred to a flask and 20 mL of acetone, 2 mL of hydrochloric acid, and 1 mL of methenamine solution were added. The mixture was kept under reflux in a boiling water bath for 30 min. The hydrolysate was filtered into a volumetric flask (100 mL) and ...
Cationic chitosan solution was prepared by dissolving 1 g chitosan powder in 100 mL distilled water with a constant stirring speed until fully dissolved. The pH of the solution was adjusted to 2–3 by the dropwise addition of dilute hydrochloric acid. Anionic sodium phytate solution was obtained ...
