Abstract
This research focuses on the study of biocomposite nanoparticles of Eleocharis dulcis (ED) as potentials biosorbent to reduce the concentration of lead (II) ion containing Sasirangan textile industry wastewater. Eleocharis dulcis, locally named as Purun Tikus, has been developing becomes the biocomposites nanomaterial and valuables material in this research. Batch experiments were carried out to considering the kinetic of biosorption of lead onto the adsorbent, evaluating the effects of lead ion equilibrium concentration, equilibrium pH, and temperature on the adsorption of lead (II). Kinetic data of lead (II) biosorption onto EDB and EDB-MH revealed that equilibrium time was reached within 2 h, and the isotherm data showed that the Langmuir maximum adsorption capacity of the EDB-M and EDB-MH at pHe of 6±0.2, room temperature were 150.43 mg/g and 180.92 mg/g, respectively. The thermodynamic of lead (II) biosorption onto the adsorbent implied the biosorption was spontaneous and endothermic indicating by increased in temperature would increased in adsorption capacity.
Highlights
Heavy metals are present harmful, carcinogenic and nonbiodegradable characteristics when they appeared in the aquatic environment
Lead is considered detected in Sasirangan textile wastewater
The Eleocharis dulcis (ED) biocomposite with iron (III) nanoparticles (EDB-M) with diameter size around 30–50 nm is a promising precursor to be used in the biosorption process for the reduction of lead from Sasirangan industrial textile wastewater
Summary
Heavy metals are present harmful, carcinogenic and nonbiodegradable characteristics when they appeared in the aquatic environment. From the point of view the heavy metals categories, lead has gained an increasing attention due to its numerous occurrence in wastewaters and its high toxicity impacts to human health [1, 2]. In Sasirangan textile wastewaters, Pb-ion concentrations approach of 2–5 mg/L. Biosorption method, a part category of adsorption, has gain concern for treatment lead– containing wastewater due to its high efficiency, easy operation, low cost, abundant amount in nature, mitigating heavy metal removal in low metal concentration (< 100 mg/L), reduced quantity of chemical and sludge handling. The agricultural biomass-derived magnetic as adsorbent would be easy separated after adsorption process from solution by using magnet kits. This research proposed Eleocharis dulcis (ED), locally named as Purun Tikus, becomes the biocomposites nanomaterial with magnetic modifiers and valuables material as an adsorbent for treating lead-containing Sasirangan textile wastewater. The contact time effect, equilibrium pH, equilibrium Pb-ion concentration, and temperature, related to kinetic and isotherm adsoprtion models, and thermodynamic parameters, such as entalphy, free energy change, and entropy were considered in batch model experiment for a more appropriate understanding of the mechanism of
