stabilization/ solidification (s/s) of hazardous waste by hydraulic binders is one of the mostpromising ways to reduce the polluting nature of ultimate waste. this study conducted at the laboratory scale, to study of the influence of various parameters namely: the ratio l/s, the contact time solid/liquid, surface and medium of exposure...etc., on the environmental impact of ultimate waste synth...

The usage of wastes of bagasse would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of bagasse-bentonite. The prepared adsorbent was applied to remove Pb2+ from aqueous solution. It was conducted in laboratory scale using completely randomized design with variations in mixed ma...

The usage of wastes of algae would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of algae waste-bentonite. The prepared adsorbent was applied to remove Pb2+ from aqueous solution. The characterization data of the adsorbent were analyzed using FTIR and SEM-EDX methods. The FTIR...

the disposed wastes of zinc industries contain large amounts of heavy metals such as pb2+ and cd2+. these elements are considered as hazardous elements to human beings and other organisms. this study aims at introducing the fungal isolates that evolved to be compatible with waste deposits during the time and can absorb pb2+ and cd2+ions. during the spring and autumn in 2011, eight samples of se...

A comparative study of the removal of Pb2+ ions and Cr3+ ions was conducted to determine the efficiency of carbon nanotubes (CNTs) produced using microwave heating as an adsorbent in removing heavy metal ions from waste water. Optimization of parameters such as adsorbent dosage, pH value, agitation speed, and agitation time was done using the Design Expert software version 6.0. The statistical ...

X-ray crystallographic structural determinations of the PB2 cap binding domain (PB2cap) have improved the conformational characterization of the RNA-dependent RNA polymerase machinery (PA, PB2, and PB1) of the influenza virus. Geometrically, the catalytic PB1 subunit resembles the palm of a human hand. PA lies near the thumb region, and PB2 lies near the finger region. PB2 binds the cap moiety ...

the aim of the present paper was to assess the maximum biochemical methane potential (bmp) of municipal solid waste. a fresh stock of the biodegradable fraction of municipal solid waste was composed based on the typical composition of biodegradable waste disposed at the landfill. bmp tests were performed under controlled conditions. the cumulative methane generation profile was corrected for me...

This study investigated the adsorption of the heavy metal ions Pb(II), Cu(II), Cd(II), Zn(II), and Ni(II) on a lignin isolated from black liquor, a waste product of the paper industry. Lignin has affinity with metal ions in the following order: Pb(II)>Cu(II)>Cd(II)>Zn(II)>Ni(II). The adsorption kinetic data can be described well with a pseudosecond-order model and the equilibrium data can be fi...

Sesame leaf, an agricultural solid waste, was used as low cost adsorbent for removal of Pb(II) from aqueous solution in batch mode. The biosorbent was characterized by thermo-gravimetric analysis and Fourier transform infrared spectroscopy. The influences of phase contact time, solution pH, adsorbent dosage, and initial concentrations were investigated to optimize the conditions for maximum ads...
