Removal of Toxic Lead from Wastewater by Seed Hull.

In this work, we address two concerns at once: waste reduction and the development of a lead removal adsorbent. The potential of seed hull (LSH) powder as an efficient, innovative, and economical adsorbent for Pb(II) absorption was examined in this study. Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscopy investigations were used to determine the structural and morphological properties of the LSH adsorbent.

Characterization of Some "Hashish" Samples in the Egyptian Illicit Trafficking Market Using a Thermal Separation Probe and Gas Chromatography-Mass Spectrometry.

Drugs that are illegal have long been a part of Egyptian society. The most widely misused form of narcotic is marijuana, also known as "bango", and other cannabis-related products like "hashish". The chemical profile of some available "hashish" in the local Egyptian illegal market and its possible country of origin are investigated using a gas chromatography-mass spectrometry technique in conjunction with a thermal separation probe (TSP/GC/MS).

Removal of synthetic reactive dyes from textile wastewater by Sorel's cement.

Removal of some reactive dyes (RY-145, RR-194 and RB-B) from textile wastewater effluents using Sorel's cement is described. Parameters affecting dye uptake including contact time, reagent dosage and pH are examined and optimized. Dye adsorption equilibrium data are fitted well to the Langmiur isotherm rather than Freundlish isotherm.

Removal of mercury(II) from wastewater using camel bone charcoal.

Camel bone charcoal is used as an adsorbent for the removal of Hg(II) from wastewater effluents. The equilibrium data are fitted to Langmiur isotherm rather than linear and Freundlich isotherms. The adsorption capacity Qo is 28.
