技术定义与适配语境
典型 氯离子 会按材料、尺寸公差、适配关系和失效风险在 化学制造 中评估。

Chloride ions (Cl⁻) are anionic components derived from chlorine that function as charge-neutralizing agents in polyaluminum chloride (PAC) coagulants. In industrial-grade PAC formulations, chloride ions help stabilize aluminum hydroxide polymers, enhance coagulation efficiency through charge neutralization of colloidal particles, and improve floc formation in water treatment processes. Their concentration typically ranges from 30-45% in commercial PAC products.

定义
Chloride ions (Cl⁻) are anionic components derived from chlorine that function as charge-neutralizing agents in polyaluminum chloride (PAC) coagulants. In industrial-grade PAC formulations, chloride ions help stabilize aluminum hydroxide polymers, enhance coagulation efficiency through charge neutralization of colloidal particles, and improve floc formation in water treatment processes. Their concentration typically ranges from 30-45% in commercial PAC products.
工作原理
Chloride ions work through electrostatic charge neutralization in water treatment. When PAC is added to water, chloride ions help maintain the positive charge density on aluminum hydroxide polymers. These positively charged polymers attract and neutralize negatively charged colloidal particles (like clay, organic matter, and microorganisms) through charge neutralization, causing destabilization and subsequent aggregation into larger flocs that can be removed by sedimentation or filtration.
材料
Industrial-grade chloride ions in PAC coagulants are typically derived from hydrochloric acid (HCl) or aluminum chloride (AlCl₃) sources. The chloride content must meet purity standards with minimal impurities like heavy metals (As < 0.0005%Pb < 0.002%) and sulfate ions (SO₄²⁻ < 3.0%).
