Municipal Solid Waste Incineration (MSWI) fly ash contains significant amounts of leachable metals, and is therefore considered as hazardous waste. The increased amounts of fly ash generated cause environmental issues, management costs and accumulation of valuable metals in landfills. All these factors contribute to an increased interest in recognizing the ash as an urban mining target of metal...

introduction: in recent years, much attention has been focused on agricultural wastes especially those containing phenolic compounds with natural antioxidant properties. one of these sources is the green husks of walnuts. the contents of phenolic compounds of plants are influenced under various factors including genetic factors, agricultural varieties and the species, climate and extraction pro...

Ultrasound-assisted extraction is evaluated as a simpler and more effective alternative to conventional extraction methods for the extraction of bioactive compounds from natural product. This study investigated the use of ultrasound-assisted extraction to extract three dibenzylbutyrolactone lignans, including tracheloside, hemislienoside, and arctiin from Hemistepta lyrata. Factors such as extr...

A novel, sensitive and effective method has been developed for preconcentration of Ni on C18 disks modified cyclodextrin–chitosan/nano graphene oxide. Simple chemical bonding method to synthesize cyclodextrin–chitosan/nano graphene oxide (CCGO) was reported. The adsorption behaviors of Ni (II) in aqueous solution on CCGO were systematically investigated. The procedure is based on the selective ...

Background & Aim: Sesame is one of the oldest cultivated plants in the world and is one of the oldest oily products used by humans. Sesame oil is an important industrial, oral and medicinal oil. Today, the use of ultrasound has grown significantly due to its effects on food storage and processing. Experimental: In this research, the response level model w...

introduction: tea (camellia sinensis), is the most widely beverage after water across the world. the most important chemical composition in tea is phenolic compounds (catechins) that have antioxidant and anticarcinogenic properties and are benefited for cardiovascular disease. there are two major kinds of tea, black tea and green tea. green tea, is originated in china and dates back to several ...

In this study, plantwide control of an absorption/stripping CO2 capture process using mono-ethanol-amine was investigated using dynamic simulation. In this system, CO2 removal ratio is influenced by operating variables such as lean solvent rate and lean solvent loading, which is in-turn determined by reboiler duty in the stripper. Moreover, we found that the long term stability of the system ca...
