Embodiment 1
[0057] Embodiment 1: research cyclodextrin can measure hydrogen sulfide ((H 2 S)) Influence
[0058] Test samples were prepared using 200 g of paper sludge obtained from a MeadWestvaco plant (Mahrt, AL.), which was added to 800 g of 50 mM phosphate buffer solution (pH 7.1). Phosphate buffer solution consists of 2.503g KH 2 PO 4 (anhydrous) / L and 5.47g K 2 HPO 4 (Anhydrous) / L mixed. Different forms of cyclodextrins, namely β-cyclodextrin and hydroxypropylated β-cyclodextrin, were detected in sludge samples at different dosage levels.
