Halloysite sorbent was added to liquid urine (dose 10 g/dm) and solid faeces (unmodified structure, dose 50 g/kg) being a subject of anaerobic fermentation in a hermetic system for 20 days. Identification of surface morphology and elementary chemical composition in microregions of the spent sorbent were done using scanning electron microscope Zeiss Supra 35 equipped with EDS detectors. Both gra...

Genomic imprinting causes the expression of an allele depending on its parental origin. In plants, most imprinted genes have been identified in Arabidopsis endosperm, a transient structure consumed by the embryo during seed formation. We identified imprinted genes in rice seed where both the endosperm and embryo are present at seed maturity. RNA was extracted from embryos and endosperm of seeds...

background: cattle can be considered as an important source for herbicides through nutrition. therefore, herbicide residue in animal products is a potential human exposure to herbicides causing public health problems in human life. triazines are a group of herbicides primarily used to control broadleaf weeds in corn and other feed ingredients and are considered as possible human carcinogens. to...

With the aim of investigating the effects of carbonaceous sorbent amendment on plant health and end point contaminant bioavailability, plant experiments were set up to grow maize (Zea mays) in soil contaminated with polycyclic aromatic hydrocarbons (PAHs) and metals. Maize and pine derived biochars, as well as a commercial grade activated carbon, were used as amendments. Plant growth characteri...

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...

A simple model for the adsorption kinetics carbon dioxide onto an amine-impregnated mesoporous sorbent, NETL-32D, was developed. The model was developed based on the mechanistic pathways believed to be responsible for the uptake of CO2 by the sorbent, including interactions with H2O. The model consists of quasi-ideal expressions to describe the kinetics of three reactions responsible for the up...

Abstract It this paper, the comprehensive design process was carried out to fabricate selective, molecularly imprinted polymer (MIP). The material used as a sorbent in optimized analytical method, aimed at verifying hypothesis that conditions of an could convert 4-hydroxyphenylacetic acid 4-hydro-3-nitrophenylacetic acid, comprising series novel studies. stage consisted analysis specificity MIP...
