摘要：

Seventy-three surfactants were selected for investigation. to assess the relation of surfactant hydronhile-lipophile balance (HLB) and surfactant chemical class unon accumulation of Fe from the chelate, FeNaHDTPA, by chrysanthemum foliage. An HLB in the range of 15 to 16 is the first criterion for selecting an effective nonionic surfactant. Chemical class should follow. The HLB relationship does not exist in the case of ionic surfactants; therefore an investigation by chemical class is the first tool. An investigation of renresentative surfactants in six ionic class categories indicated that the sulfate, amide, and quaternary ammonium chloride categories were relatively inactive. A few active surfactants were found among the sulfonated and amine categories. The most active category was phosphate surfactants. Ten surfactants increased Fe accumulation 2.5-fold or more and were not phytotoxic. © 1969, American Chemical Society. All rights reserved.
