Dai, Yingjie published the artcileNew use for spent coffee ground as an adsorbent for tetracycline removal in water, HPLC of Formula: 111-87-5, the main research area is SCG adsorbent tetracycline removal water adsorption wastewater treatment; Hydrogen bond; Hydrophobic interaction; Oxygen-containing functional groups; Removal ratio; π–π interaction.
Spent coffee grounds (SCG-1 and SCG-2) were used to study the adsorption of tetracycline (TC) antibiotics and the effects of adsorption time, initial pH, amount of adsorbent and ionic strength were detected. The TC adsorption isotherm on SCG-1 was compared with SCG-2. The results showed that the removal efficiencies of TC (50 mg/L) of SCG-1 and SCG-2 were 83.1% and 97.2%, resp., shake for 2 h. The probability of adsorption is high and balances in about 20 min. The estimate of parameters got for TC from the Langmuir isotherm saturated adsorption quantity and adsorption balance constant were 64.89 mg/g, 0.0557 L/mg, resp. for SCG-1 and 123.46 mg/g, 0.4735 L/mg, resp. for SCG-2. The adsorption mechanism might be a π-π interaction that occurs in the interface by hydrogen bonding and the between the TC mol. and the SCGs. At last, we found that SCG has a high adsorption size for TC.
