Abstract:

Bio-succinic acid (SA) is a new compound that will replace petroleum based succinic acid. The application of bio-based succinic acid is still restricted due to its excessive downstream processing cost. Liquid-liquid extraction (LLE) is one of the promising methods for the successful extraction of SA. Single extractant in the LLE formulation commonly had drawbacks of long extraction time and tiny loading capacity. The aim of this study is to create synergistic formulation to enhance the SA extraction performance. The diluent is fixed as palm oil as the characteristic shows that it is safer, ren

Abstract:

Tetracycline antibiotic (TCA) is a broad-spectrum antibiotic that is extensively utilized in agriculture and human therapy. However, its extensive use poses significant environmental risks. Extractive extraction stands out as one of the effective methods available for TCA removal from aqueous solutions. The use of a single extractant in extractive extraction requires a high extractant concentration due to its low loading capacity. Therefore, this study aims to formulate a synergistic extractant diluted in green diluent (i.e., cooking palm oil). The synergistic extractant provides a high loadin

Methodology: In order to improve extraction efficiency, di-(2-ethylhexyl) phosphoric acid (D2EHPA) was mixed with isodecanol to provide a synergistic effect together with leaching solution which is thiourea. From the single extraction system, the optimum temperature is found at 30°C producing the highest yield of %E of 91.30%.

Taxanes are the best-known compounds in Taxus cuspidata owing to their strong anticancer effects. However, the traditional taxanes extraction method is the solid–liquid extraction method, which is limited by a large energy consumption and low yield.

Abstract:

Nutmeg seeds contain essential oils and fats, are widely used in the cosmetic and pharmaceutical industries. This research aims to determine the yield, physicochemical characteristics and fat composition of nutmeg seeds extracted from Ultrasonic-Microwave Extraction (UMAE). The research used a factorial completely randomized design (CRD) method with the independent variables, length of extraction time (45, 90, 135 minutes) and microwave power (300 and 450 watts). The dependent variables in this research are yield, melting point, specific gravity, acid number and saponification number. The resu

Abstract:

To reduce the issues of high pollutant emissions and lengthy processes in extracting zinc from zinc sulfide ore, a new technical approach is proposed that involves the synergistic use of iron oxide and vacuum carbothermal reduction to extract zinc from zinc sulfide ore. The iron oxide is sourced from high-iron-content metallurgical residue. Under vacuum conditions, carbon reduces iron oxide to metallic iron, which then displaces zinc in sulfide to produce zinc vapor. The zinc vapor is finally condensed to obtain metallic zinc. This study investigates the extraction of zinc from zinc sulfide un

Abstract:

In this paper, the response surface methodology (RSM) was proposed for studying the synergistic extraction of chromium(III) ions by double-carrier supported liquid membrane (DCSLM) with organophosphorus carriers (D2EHPA/Cyanex272). At first, the optimization method of “one-factor-at-a-time” was adopted for determination of the best conditions for Cr(III) extraction by SLM with only one carrier (D2EHPA). The optimum/threshold D2EHPA concentration in the membrane phase increased linearly with initial concentration of Cr(III) ions in the feed phase. After the addition the second carrier (Cyanex27

The aims of this work were to evaluate the synergistic antioxidant activity and optimize microwave-assisted extraction of Caesalpinia sappan L., Hibiscus sabdariffa L., and Clitoria ternatea L. combinations. The simplex lattice design was applied to evaluate the synergistic antioxidant activity. The mass ratios of the 3 plants that exhibited synergistic antioxidant activity were further used to investigate the optimal condition of microwave-assisted extraction by Box-Behnken design. Results showed that the synergistic antioxidant activity among the 3 plants: Which was determined by the combina

Abstract:

Single flotation collector can not effectively extract the various valuable minerals from the complex ores simultaneously. Combined use of many collectors is one of the best ways to solve the problem, because the synergistic effect induced by the multifunctional composite chemical reagents will exert positive effect to the flotation and increase the recovery. The synergy is related with the reagent types, characteristics, and component contents in the mixture, and it is critical to choose and design the combination of various reagents. The maximal effect from synergy can be obtained easily by

Abstract:

The popularization of electric vehicles drives the extensive use of power lithium-ion batteries (LIBs) and their abandonment after retirement. Spent power LIBs have a high economic value because they contain valuable metals which need to be recovered. In this study, the separation and comprehensive recovery of valuable metallic elements, including Co, Ni, and Li, from spent power LIBs were realized by a hydrometallurgical process of “calcination–leaching–synergistic extraction–synthesis”. The results showed that, under the optimal conditions, the extraction efficiencies of impurities, such as

The results of rhenium (VII) solvent extraction with synergistic mixtures of octyl alcohol and ketone from the high acid chloride and sulphate solutions with high accompanying metals (platinum and molybdenum) content, obtained from leaching of rhenium-containing wastes, were presented. It is shown that synergistic coefficients at rhenium solvent extraction by mixtures of 30–50 % v/v 2-octanol in 2-octanone were not exceeded 1.2–1.3. However, such mixtures recovered fewer impurities of Pt (IV) and Mo (VI), and the separation factors reached 16.0 and 573.2. Besides, mixtures of alcohol and keton
