In this work, a metal–organic framework (MOF), copper benzene dicarboxylate (Cu-MOF), was tested for the adsorptive recovery of organic dyes (Sunset Yellow FCF, Tartrazine, Orange II, and Methyl Orange) from aqueous solutions. Studies were also carried out to determine effects various parameters, isothermal kinetic models proposed. The adsorption capacity Cu-MOF much higher than that activated ...

This study aims to determine the earnings management conducted by company whether it is efficient or opportunistic management, because common and often done companies what factors influence behavior of company. To find out type carried company, will be measured using Accrual Discretion (DA), while measuring that uses Profitability (Return On Assets (ROA)), Liquidity (Current Ratio (CR)), Free C...

This study examined differences in the adsorption kinetics, isotherms, and thermodynamics of dyes (methyl orange fast green FCF) by pristine (M–biochar) chemical activated mandarin peel biochars (MN–biochar MZ–biochar). The specific surface area (1085.0 m2/g) pore volume (0.194 cm3/g) MZ-biochar much higher than those M–biochar (specific = 8.5 m2/g, 0.016 MN–biochar 181.1 0.031 cm3/g). equilibr...
