Abstract: Among different ordered mesoporous silicas, SBA-type silicas are the most frequently studied. SBA-15 is an interesting mesoporous silica material having highly ordered nanosize pores and a large surface area so is widely used as absorbents, catalyst supports and drug delivery materials. Alginate as suitable biopolymer supporters improves the inappropriate physical form of mesoporous SBA-15 for practical purposes. Immobilization in polymeric matrix increases the chemical and mechanical stability of mesoporous SBA-15. Influence of synthesis conditions on adsorption capacity of SBA-15/alginate adsorbent for removal ions of nickel (II) and lead (II) from aqueous solution was investigated. Two forms of SBA-15/alginate adsorbent were prepared. Alginate gel was prepared using calcium chloride solution. Adsorption capacity behavior ions of nickel (II) and lead (II) on the two types of SBA-15/alginate adsorbent was carried out using inductively coupled plasma optical emission spectrometry (ICP-OES). Obtained results were compared with results for similar SBA-15/alginate adsorbents.
