Microalgae are small in size with negatively charged surface. They are usually stable in suspension culture and hard to flocculate. The present work emphasizes on the synthesis of cationic guar gum (CGG) by the introduction of quaternary amine groups onto the backbone of guar gum (GG) from N-(3-chloro-2-hydroxypropyl) trimethyl ammonium chloride (CHPTAC). The optimal dosage of the synthesized cationic guar gum is used to flocculate two different green algae viz. Chlorella sp. CB4 and Chlamydomonas sp. CRP7.
微藻体积小，表面带负电荷。它们通常在悬浮培养中稳定，难以絮凝。本工作强调通过将季铵基团引入瓜尔胶（GG）的主链，从 N-（3-氯-2-羟丙基）三甲基氯化铵（CHPTAC）合成阳离子瓜尔胶（CGG）。所合成的阳离子瓜尔胶的最佳用量用于絮凝两种不同的绿藻，即小球藻 CB4 和衣藻 CRP7。
