Adsorption is one of the widely used processes in the chemical industry environmental application. As compared to mathematical models proposed to describe batch adsorption in terms of isotherm and kinetic behavior, insufficient models are available to describe and predict fixed-bed or column adsorption, though the latter one is the main option in practical application. The present review first provides a brief summary on basic concepts and mathematic models to describe the mass transfer and isotherm behavior of batch adsorption, which dominate the column adsorption behavior in nature. Afterwards, the widely used models developed to predict the breakthrough curve, i.e., the general rate models, linear driving force (LDF) model, wave propagation theory model, constant pattern model, Clark model, Thomas model, Bohart-Adams model, Yoon-Nelson model, Wang model, Wolborska model, and modified dose-response model, are briefly introduced from the mechanism and mathematical viewpoint. Their basic characteristics, including the advantages and inherit shortcomings, are also discussed. This review could help those interested in column adsorption to reasonably choose or develop an accurate and convenient model for their study and practical application.

Since the realization in the 1930s that elevated fluoride concentrations in drinking water can have detrimental effects on human health, new methods have been progressively developed in order to reduce fluoride to acceptable levels. In the developing world the necessity for filtration media that are both low-cost and sourced from locally available materials has resulted in the widespread use of bone char. Since the early 1990s metallic iron (Fe 0 ) has received widespread use as both an adsorbent and a reducing agent for the removal of a wide range of contaminant species from water. The ion-selectivity of Fe 0 is dictated by the positively charged surface of iron (hydr)oxides at circumneutral pH. This suggests that Fe 0 could potentially be applied as suitable filter media for the negatively charged fluoride ion. This communication seeks to demonstrate from a theoretical basis and using empirical data from the literature the suitability of Fe 0 filters for fluoride removal. The work concludes that Fe 0 -bearing materials, such as steel wool, hold good promise as low-cost, readily available and highly effective decentralized fluoride treatment materials.

“…Berbagai metode telah dilakukan oleh para ahli untuk mengurangi cemaran logam berat, tetapi metodemetode yang digunakan tersebut umumnya baru bisa diterapkan pada lingkungan perairan bukan pada produk perikanan. Beberapa metode yang digunakan dalam menghilangkan cemaran logam berat terlarut diantaranya adalah dengan cara pengendapan, penukar ion, filtrasi membran, reduksi elektrolitik, dan adsorbsi (Kurniawan et al, 2006;Wang et al, 2003).…”

ABSTRAKKandungan logam berat yang terdapat dalam jumlah yang kecil di perairan dibutuhkan oleh makhluk hidup, tetapi dalam jumlah besar dapat menyebabkan berbagai masalah. Kehadiran industri berperan dalam meningkatkan cemaran logam berat. Berbagai cara telah dilakukan untuk mengurangi cemaran logam berat. Metode adsorbsi adalah cara yang banyak digunakan untuk mengurangi cemaran logam berat, karena aplikasinya yang cukup luas untuk berbagai jenis logam berat. Beberapa bahan alami yang ramah lingkungan seperti kitosan dan selulosa dapat digunakan sebagai adsorben. Baik kitosan maupun selulosa harus melewati tahap modifikasi untuk meningkatkan efektifitasnya sebelum digunakan sebagai adsorben.
