本研究的主要目的是探讨铁和锰对卤乙酸（哈斯）的形成，当藻类在不同的pH值氯化的作用。结果表明，铁、锰对氯化绿色小球藻（Chlorella vulgaris，C.）在pH 6.0-9.0范围内，DCAA和TCAA的下降幅度在低pH范围内更为显著。在pH 6.0时，添加0.5mgL-1铁，DCAA和TCAA产量分别下降44.5%和57.3%;添加0.5mgL-1锰，DCAA和TCAA产量分别下降39.5%和49.4%。扫描电子显微镜（SEM）分析表明，造成哈斯产率下降的主要原因是Fe（OH）3（am）或MnO 2（am）包覆在藻细胞表面，促进了藻细胞的团聚，激光粒度分析（LPSA）也表明了这一点。
The major objective of the present study was to investigate the role of iron and manganese on the formation of haloacetic acids (HAAs) when algae are chlorinated at different pHs. The results showed that both iron and manganese can reduce the yields of dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) on chlorinating green alga Chlorella vulgaris (C. vulgaris) at a pH range of 6.0–9.0, and the decline of DCAA and TCAA was shown to be more significant at the low pH range. At pH 6.0, DCAA and TCAA yields decreased by 44.5% and 57.3%, respectively with the addition of 0.5mgL−1iron, and decreased 39.5% and 49.4%, respectively with the addition of 0.5mgL−1manganese. The main reason for decreasing the yields of HAAs as shown by scanning electron microscope (SEM) is that Fe(OH)3(am)or MnO2(am)coat the algal cells,which then improves their agglomeration of algal cells which is also revealed by the laser particle size analysis (LPSA).
