ccidents resulting from construction activities as one of the main reasons causing disability or death in the developing and

developed countries has been and identify the factors that are involved in creating the events of the main measures to control and

reduce the risk is considered. In this study, all workers were employed in construction jobs during the years 2011 to 2014 employment

accident and managing events in Yazd labor and Social Affairs has been recorded in the study have been recorded with the Check list

of required information and data were then analyzed. Mean age of 34 years of study, the majority of subjects were male, and lower

education levels than victims of associate degrees, Most time the incident was 13-7, the most injured part of the hands and feet, the

most important event foul in or between objects and machines and building more factories owned (private) and cause lack of control

the employer has happened. Using the correct and efficient programs, health education and greater emphasis on compliance with

existing regulations could be more professional construction accidents could be prevented.

Linn was adopted for preparation of activated carbon

(KAC) with high capacity for amoxicillin antibiotic (AMX). The characteristics of KAC were examined by proximate and pore

structure analyses, scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). The ash and moisture

contents of KAC were 5.5 and 0.5 % compared to 2.2 and 2.1 % for raw biomass. The BET surface area and total pore volume were

identified to be 1065.3 m²/g and 0.643 cm³/g, respectively. The best preparation conditions in terms of KAC yield and AMX uptake

were reported as 10 min radiation time, 620 W radiation power and 2 g/g impregnation ratio resulted in 9.1 % yield and 196.9 mg/g

AMX uptake. Experimental equilibrium data for AMX adsorption were analyzed by Langmuir, Freundlich, and Sips isotherms. The

results showed that the best fitting was achieved by Sips isotherm with high adsorption capacity of 345.4 mg/g on KAC compared

to 75.8 mg/g on precursor. Also, kinetic data were correlated by pseudo-first order, pseudo-second order, and intraparticle diffusion

models with well-fitting to pseudo-second order model. Thermodynamic analysis showed that adsorption enthalpy of AMX was 17.7

kJ/mol which revealed endothermic and physisorptive nature under examined conditions.
