In this study, chitosan (CTS) was crosslinked with both epichlorohydrin (ECH) and triphosphate (TPP), by covalent ionic crosslinking reactions, respectively. The resulting adsorbent (CTS–ECH–TPP) characterized SEM, CHN, EDS, FT-IR TGA analyses, tested for metal adsorption. used in batch experiments to evaluate the adsorption of Cu(II) Cd(II) ions single binary solutions. solutions maximum capacities ions, obtained Langmuir model, were 130.72 83.75 mg g−1, Adsorption isotherms showed that...
ABSTRACT: The Basaltic Hillsides region spans a vast area in western Santa Catarina State, Brazil, consisting of magmatic flows from the Serra Geral Group. This study analyzed soil levels Ba, Cd, Ni, Cu, Zn, Cr, Pb, Mn, and Co these hillsides, comparing them to reference values set by current legislation for Catarina. Pearson correlation analysis hierarchical dendrogram were conducted based on results frommultiple studies employing consistent methodologies. Nearly all trace elements showed...
ABSTRACT Differences in hoof balance between horses, mules and donkeys were identified order to form more specific considerations for proper management of the animals. Measurements natural dimensions hooves sixty animals used: 20 horses from Crioulo breed, Pêga breed. Liveweight was estimated using correlation equations each species by heart girth. Using a caliper rule, tape measure gauge, measurements length width frog, height, angle heel, medial lateral dorsal length, toe crown...
CONTAMINATED IN COAL MINING.Considerable attention has been paid to chitosan and derivatives as efficient adsorbents of pollutants such metal ions dyes in aqueous medium.Nevertheless, no report can be found on the remedial actions microspheres crosslinked with tripolyphosphate control acidity, iron (III) manganese (II) contents wastewaters from coal mining.In this work, were used for neutralization acidity removal Fe Mn mining wastewaters.The study involved static dinamic methods.The...
Abstract The coal industry may generate acid mine drainage (AMD) and mining wastes, which adversely affect the quality of environment. In this study we propose use waste in removal acidity metal ions, as well reduction toxicity AMD. A physico‐chemical analysis shows presence mainly SiO2, Al2O3 Fe2O3 a superficial area 4.316 m2 g−1. treatment AMD with resulted an increase pH from 2.6 to 7.8 removed 100% Al (III), Fe (III) 89% Mn (II). We also observed that high towards Daphnia magna (LC50 =...
Abstract Chitosan microspheres are highly effective in neutralizing the acidity of wastewaters from coal mining. The saturation capacity for formation a superficial monolayer on adsorbent was interpreted using Langmuir isotherm and considering amino groups as adsorption sites hydronium ions. surface static system 0.428 mol kg-1, higher than that dynamic one. This value corresponds to neutralization 135 liters wastewater per kilogram microspheres. One gram chitosan capable increasing pH 2.5...
ADSORBENT FOR REMOVAL OF ACIDITY, Fe (III), Al (III) and Mn (II) IN ACID DRAINAGE.This study aimed the use of coal mining waste as a new adsorbent for H 3 O + removal from acid mine drainage.Data kinetic equilibrium adsorption followed pseudo second-order Langmuir isotherm models.The maximum capacity was 316 mmol kg -1 .The removed 100% 89% (II), suggesting its an alternative treatment drainage.
This study aimed to measure the concentrations of minerals in different regions and pigmentation horses' hooves, mules donkeys.A total 20 Crioulo horses, Pega donkeys were used.They formed two groups: pigmented (dark) or non-pigmented (bright) hooves.All animals unshod with adequate foot conformation.Females nonpregnant without foal no training.Samples collected from hooves all limbs wall, sole frog.The calcium, magnesium, copper, iron zinc determined by atomic absorption spectrophotometry;...
SELF-ASSOCIATION OF SODIUM DODECANOATE (SDoD) AND DECANOATE (SDeC) WITH THE HYDROPHOBICALLY MODIFIED POLYMER ETHYL(HYDROXYETHYL)CELLULOSE (EHEC).In this work, the interactions between non-ionic polymer of ethyl(hydroxyethyl)cellulose (EHEC) and mixed anionic surfactant sodium dodecanoate (SDoD)sodium decanoate in aqueous media, at pH 9.2 (20 mM borate/NaOH buffer) were investigated by electric conductivity light transmittance measurements 25 ºC.The parameters to association processes such as...
The Campeiro horses descend from animals brought into southern Brazil by Spaniards between the sixteenth and seventeenth centuries.They have shown adaptations to local climatic conditions, types of feeding, management, selection models which they been exposed over years.This study aims investigate characteristics hooves horse means morphometry measurement contents some minerals propose an approach assess balance palmar/plantar region hooves.Hoof data fore hind 50 were recorded.The...
The aim of this work was to evaluate the effects chitosan emulsion (CE) in combination with essential oils (Eos) on blue mold control, as well aroma and quality attributes “Fuji” apples after storage. Treatments evaluated were CE (1%) combined citronella, clove copaiba EOs (all at 500 μl L−1). Fruits treated EC + OEs showed lower total phenolic compounds peel all treatments. citronella (242.4 OD mg–1 protein min–1) (205.8 peroxidase activity fruit tissue. Therefore, reduced development...
