【摘要】 <正> 用卟啉衍生物光度法测定镉的研究已有报导。我们采用α,β,γ,δ-四-(4-氯苯基)卟啉[简称T(4-Cl)PP]在适当掩蔽剂存在下直接测定水样中的微量镉,结果令人满意。 (一)主要试剂及仪器更多还原

【Abstract】 In this paper, the complex formation reaction of α,β,γ,δ-tetra-(4-chlor-ophenyl) porphine CT(4-Cl)PPD with Cadmium in the presence of mixture surfactant, sodium dodecyl benzene sulfonate and tritonX-100 was studied, and a new highly sensitive method for spectrophotometric determination of micro amounts of cadmium has been developed, utilizing the soret band of the cadmium-T( 4-Cl )PP complex. Apparent molar absorption coefficient is 4.1 × 105.更多还原
