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

In this study 10 guaianolide-type sesquiterpene g-lactones named amphoricarpolides, isolated from the aerial parts of two endemic subspecies of Amphoricarpos neumayeri (ssp. neumayeri and ssp. murbeckii Bošnjak), were investigated by means of reversed-phase thin-layer chromatography. Methanol–water and tetrahydrofuran–water binary mixtures were used as mobile phase in order to determine lipophilicity parameters RM0 and C0. Some of the investigated compounds were screened for their cytotoxic activity against HeLa and B16 cells. Chromatographically obtained lipophilicity parameters were correlated with calculated logP values and IC50 values. Principal component analysis identified the dominant pattern in the chromatographically obtained data.
