Recently, there is a growing research interest in the applications and development of novel sustainable hydrogel materials in waste water treatment because of radically distinctive chemical and physical characteristics of hydrogels such as hydrophilicity, swell ability and modifiability to name a few. Hydrogels have exposed the hypernym functioning in the removal of a wide range of aqueous pollutants containing toxic dyes and heavy metal ions. A large amount of water gets incorporated in the three dimensional networks of hydrophilic structures of hydrogels. The prime objective of this review article is to render a presentation on the recent advances in the modifications of sodium alginate based hydrogels for the adsorptive removal of toxic pollutants. In addition, article also briefly gives the classification and properties of hydrogels and alginate.

Makale BilgisiÖz Bu çalışmada Polianilin/Aljinat (PANİ/SA) adsorbent malzemesi Asit Violet 90 (AV 90) boyar maddesinin adsorpsiyonunda kullanılmıştır. PANİ/SA'nın karakterizasyonu Fourier Dönüşüm Kızılötesi Spektroskopisi (FTIR) ile analiz edilmiştir. pH (2-6), PANİ/SA küre sayısı (10-50 adet) ve AV 90 derişiminin (25-200 mg/L) boyar madde giderimine etkisi incelenmiştir. En yüksek boyar madde giderimi pH 2'de elde edilmiştir. AV 90 adsorpsiyon izotermlerini belirlemek için Langmuir, Freundlich ve Temkin modelleri kullanılmıştır. Boyar madde derişimi 25-200 mg/L aralığında iken Langmuir modelinden elde edilen maksimum adsorpsiyon kapasitesi (qm) değeri 138,9 mg/g olarak bulunmuştur. Adsorpsiyon kinetiğinin belirlenmesi için Yalancı birinci derece ve ikinci derece kinetik modelleri kullanılmış ve Yalancı ikinci derece kinetik modelin deney verileri ile daha uyumlu olduğu görülmüştür. Deney sonuçları PANİ/SA adsorbentinin AV 90 boyar maddesinin adsorpsiyonu için oldukça iyi bir alternatif olduğunu göstermiştir. AbstractIn this study, Polyaniline/Alginate (PANI/SA) material was used to adsorption of Acid Violet 90 (AV 90) dye. The characterization of PANI/SA was analyzed by Fourier transform infrared spectroscopy (FTIR). The effect of pH (2-6), number of PANI/SA beads (10-50 adet) and concentration of AV 90 (25-200 mg/L) on removal of dye were examined. The highest dye removal was obtained at pH 2. Langmuir, Freundlich and Temkin models were used to determine AV 90 adsorption isotherms. The maximum adsorption capacity (qm) value obtained from the Langmuir model in the range of 25-200 mg/L dye concentrations was found to be 138.9 mg / g. To determine the adsorption kinetics, Pseudo first order and second order kinetic models were used and it was found that the Pseudo second order kinetic model was more compatible with the experimental data. Experimental results have shown that PANI/SA adsorbent is a very good alternative for adsorption of AV 90 dye.
