“…To further understand the adsorption selectivity of various metal-ion solutions, Pb(II) and Zn(II) were selected as coexisting ions to calculate the distribution coefficient K d . This index is usually used to compare the retention capacity of specific adsorbents to various metal ions in the multisolute system . Therefore, the K d values at the initial concentration of 60 mg/L for each metal ion were used to compare the retention capacity of metal ions in the single-metal solution and the ternary metal solution.…”

In this work, the adsorbent based on tannin (TN) and polyethylenimine (PEI) was prepared via a simple and green method (TNP). The characteristics of the TNP were determined using scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy, and the results revealed that TNP was synthesized by TN and PEI, and Cu(II) was combined with the −NH or −OH groups of TNP. The effects of the n (TN) :n (PEI) , adsorbent dosage, pH, time, initial metal concentration, and temperature on the adsorption of Cu(II) were investigated in detail. The adsorption of Cu(II) by TNP was greatly affected by pH, and n (TN) :n (PEI) = 1.5:3 was the optimum mole ratio of raw material to obtain TNP. TNP possessed excellent adsorption properties, and the maximum adsorption capacity of TNP for Cu(II) was 94.5 mg/g at 338.15 K. The adsorption process was in agreement with the Langmuir model and the pseudo-second-order model. Regeneration and reusability of TNP did not decrease significantly after four times of regeneration experiments. The order of competitive ability for the three metal ions was as follows: Pb(II) > Cu(II) > Zn(II). These experimental results suggested that TNP could effectively remove metal ions from aqueous solution. This study is of great significance for environmental protection.

As a center of textile industry in Indonesia, city of Pekalongan faces environmental issue due to wastewater effluent from textile industry. The wastewater from textile industry contains dye, mostly synthetic dye, used for coloring the fabrics. One of the dyes commonly used is sulphur blue for producing dark blue color. One of simple methods to reduce the dye in the wastewater is adsorption. Cuttlefish bone was used as the adsorbent. It is abundantly available and cheap because it is a waste of fishing industry. The effect of acid and alkaline treatment to the cuttlefish bone on its adsorption capacity toward sulphur blue dye was investigated. The acid and alkaline treatments were conducted using hydrochloric and sodium hydrochloric solutions, respectively. The concentrations of both solutions were varied (0.0 N, 0.25 N, 0.5 N, 0.75 N, 1.0 N). The concentration of acid and alkaline affect the adsorption capacity of the cuttlefish bone. The cuttlefish bone treated with 0.25 N hydrochloric solution is able to reduce the concentration of the dye solution from 217.67 to 87.67 Pt-Co, while that treated with 0.25N sodium hydroxide solution lowers the concentration of the dye solution to 74.33 Pt-Co. The alkaline-treated cuttlefish bone showed higher adsorption capacity than the acid-treated cuttlefish bone.
