This study presents the adsorption capability of a filter composed sand coated with cobalt nanomaterials (CoNM) for extraction manganese ions from aqueous media. The was performed in both batch and dynamic modes order to evaluate capabilities free-standing CoNM CoNM-coated sand. Langmuir Freundlich isotherm models were applied batch-mode. model estimated maximum capacity 17.86 mg/g correspondin...

This paper investigates anaerobic co-digestion of pig manure and algae (Scenedesmus sp.) with and without extraction of intracellular algal co-products, with views towards the development of a biorefinery concept for lipid, protein and/or biogas production. Protein and/or lipids were extracted from Scenedesmus sp. using free nitrous acid pre-treatments and solvent-based Soxhlet extraction, resp...

Bcakground: Extracts obtained from natural sources such as plants are of immense importance for humans. Methods: Therefore this study was conducted to obtain essential oil from the seeds of T. ammi by conventional and non-conventional methods. Hydrodistillation (HD), Solvent Extraction (SE), Ultrasonication (US), and Supercritical Carbon-dioxide (SC-CO₂) extraction techniques were used to extra...

Current extraction methods often extract DNA and RNA separately, and few methods are capable of co-extracting DNA and RNA from sputum. We established a nucleic acid co-extraction method from sputum based on magnetic beads and optimized the method by evaluating influencing factors, such as the guanidinium thiocyanate (GTC) and dithiothreitol (DTT) concentrations, magnetic bead amount, incubation...

208 The natural food colorants, carotenoids, are of great importance to human health. The scientists at Department of Agricultural, Food and Nutritional Science, University of Alberta, Canada enhanced the efficiency of SC-CO 2 extraction of carotenoids from carrots, by using canola oil as a continuous cosolvent. The carotenoid content of the starting material was determined by traditional solve...

Geometric co-registration errors and results of object extraction (such as classification and pattern recognition) are the two main factors, which greatly affect the results of change detection in traditional methods. Unfortunately, the geometric co-registration accuracy and results obtained by the object extraction methods can not satisfy imagery change detection in practice at present. Consid...

Phosphorus (P) can be effectively recovered from sewage sludge ash (SSA) by applying wet chemical extraction techniques. However, considerable amounts of heavy metals co-extracted depending on the type liquid used. In this study, influence incineration temperature mineralogy and related P metal using sulfuric acid, hydrochloric oxalic acid sodium hydroxide was studied. Results showed that effic...

Biodiesel is considered a promising replacement to petroleum-derived diesel. Using oils extracted from agricultural crops competes with their use as food and cannot realistically satisfy the global demand of diesel-fuel requirements. On the other hand, microalgae, which have a much higher oil yield per hectare, compared to oil crops, appear to be a source that has the potential to completely re...
