REMOVAL OF SYNTHETIC DYE ACID RED 186 FROM WATER BY ACTIVATED CARBON

The adsorption of acid red 186(AR) onto activated carbon prepared from Libyan farms was studied, the effect of solution pH, contact time, adsorption dose and initial dye concentration was evaluated. The adsorption studied included Langmuir and Freundlish isotherms were applied to experimental results. The experimental results fitted very well to both adsorption isotherms. The mixture mono layer capacity obtained from Langmuir is q_e =7.62mg/g for activated carbon (100-45um) and q_e=7.194mg/g for activated carbon (lees than 45um).Therefore, activated carbon has the potential to be used as a low cost eco-friendly adsorbent for removal “activated carbon” dye from aqueous solution. arabic 11 English 57

Determination of Some Trace Elements in Different Vinegar Samples from Libyan Market using Inductively Coupled Plasma Atomic Emission Spectrometer ICP-AES

Ten vinegar samples were collected from the Libyan local market in the city of Tripoli. The elements have been investigated were:As, Pb, Cu, Fe and Zn. The samples were treated and prepared according to Indian standard IS 14703-1999, and the measurements have been done by using inductively coupled plasm – atomic emission spectroscopy (ICP-AES) available in the Libyan Petroleum Institute. The analysis indicated that the concentration of Arsenic of all the samples was less than 0.02mg/kg whereas, the concentration of lead is less than 0.03mg/kg. The concentration ranges of Cu, Fe and Zn were 0.11-0.59mg/kg, 0.72-2.67mg/kg and 0.08-0.28mg/kg respectively. The concentrations of the elements AS, Pb, Cu, Fe and Zn are within the limits of a variety of standards such as Libyan, Indian and Pakistani ones. arabic 21 English 134
