a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...

The mechanism of hydrothermal liquefaction of cypress was investigated by examining the effects of temperature and retention time on the characteristics of the solid residues remaining after liquefaction. The solid residues were divided into acid-soluble and acid-insoluble residues. Results showed the polymerization reactions also mainly occurred at low temperatures. The reactive fragments tran...

abstract: using agricultural waste is one of the best ways to reduce the costs and the environmental pollution. button mushroom´s stipe is a cheap by-product that is rich in nutrients for human nutrition. the purpose of this study is to compare the nutritional value of cap and stipe of button mushroom (agaricus bisporus). the caps were separated from the stipes after harvesting and parameters s...

Remediation of heavy metal polluted sediment by extracting the metals with sulfuric acid can be performed as follows: abiotic suspension leaching, microbial suspension leaching, abiotic solid-bed leaching, and microbial solid-bed leaching. Abiotic leaching means that the acid is directly added, while microbial leaching means that the acid is generated from sulfur by microbes (bioleaching). Thes...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...

sulfonic acid functionalized sba-15 (sba-pr-so3h) as a new nanoporous acid catalyst was used in the one-pot synthesis of polyhydroquinolines derivatives via the hantzsch four component condensation reaction of aldehydes, b-ketoesters, dimedone and ammonium acetate under solvent free conditions with short reaction time in excellent yields. sba-pr-so3h was proved to be an efficient heterogeneous ...
