Son yıllarda düşük maliyetli tarımsal atıklar kullanılarak ağır metallerin sulardan uzaklaştırılması çalışmaları hız kazanmıştır. Zeytinyağı endüstrisi atığı olan pirinanın (zeytin posası) adsorban olarak kullanılmasıyla sularda çözünmüş Cr(VI) ve Cu(II) ağır metallerinin giderimi araştırılmıştır. Deneysel adsorpsiyon prosesinde, sıcaklık  (20oC), adsorban dozu (0.5 g) ve partikül boyutu (0.5-2.0 mm) sabit tutularak; giderim verimine Ph (2-6),  temas süresi (2-120 dk) ve başlangıç ağır metal konsantrasyonlarının (5-100 mg/L) etkileri incelenmiştir. pH 4, temas süresi 15 dk ve başlangıç ağır metal konsantrasyonu 5 mg/L’de aktifleştirilmiş pirina (AP) kullanılarak Cr(VI) ve Cu(II) maksimum giderimleri %98.8 ve %93.2 olarak elde edilmiştir. Bu sonuçlar doğrultusunda Cr(VI) ve Cu(II) için adsorplanma kapasiteleri 0.988 mg/g ve 0.932 mg/g olarak tespit edilmiştir. Ayrıca, optimum koşullarda kinetik ve izoterm modelleri uygulanmış olup; deneysel .sonuçlar ile yalancı ikinci derece kinetik ve Langmuir izoterm modellerindeki teorik sonuçlar arasında iyi bir uyum gözlenmiştir. FTIR analizi ile çeşitli fonksiyonel gruplar tanımlanmış ve SEM görüntüleri AP’nin gözenekli yapıya sahip olduğunu göstermiştir. Çalışma sonuçları, adsorpsiyon uygulamalarında AP’nin düşük maliyetli adsorban olarak çeşitli alanlarda kullanıma uygunluğunu ispatlamıştır.
