In order to solve the problem of fluorine-containing water pollution, lanthanum chloride precipitation method was used to remove fluorine from it. Through in-depth analysis of the chemical characteristics and thermodynamic reaction mechanism of the solution, the interaction between La3+ and F- in aqueous solution was revealed. The effects of initial pH of the solution, the amount of lanthanum chloride, reaction temperature and time on the removal of fluoride were investigated by single factor test, and the optimized process parameters were determined. The results show that for the fluorine-containing simulated solution with fluorine ion mass concentration of 0.1-1.0 g/L, under the conditions of initial solution pH of 3.0, lanthanum chloride dosage of 1.3 times of the theoretical amount, reaction temperature of 50 ℃ and reaction time of 10 min, the fluorine removal rate is more than 95%, and the residual fluorine ion mass concentration in the liquid after fluorine removal is less than 30 mg/L, which meets the fluoride emission limit specified in the national standard. The method has good process applicability in a wide range of fluorine concentration and has certain application value.

针对含氟水体污染问题,研究了采用氯化镧沉淀法去除其中的氟。通过深入剖析溶液化学特性与热力学反应机制,揭示了La3+与F-在水溶液中的相互作用规律,并采用单因素试验考察了溶液初始pH、氯化镧用量、反应温度及时间等对除氟效果的影响,确定了优化工艺参数。结果表明:针对氟离子质量浓度为0.1~1.0 g/L的含氟模拟溶液,在溶液初始pH为3.0、氯化镧用量为理论量的1.3倍、反应温度为50 ℃、反应时间为10 min条件下,除氟率达95%以上,除氟后液中剩余氟离子质量浓度低于30 mg/L,符合国标规定的氟化物排放限值。该法在较宽的氟浓度范围内具有较好的工艺适用性,具有一定应用价值。

针对含氟水体污染问题,研究了采用氯化镧沉淀法去除其中的氟。通过深入剖析溶液化学特性与热力学反应机制,揭示了La3+与F-在水溶液中的相互作用规律,并采用单因素试验考察了溶液初始pH、氯化镧用量、反应温度及时间等对除氟效果的影响,确定了优化工艺参数。结果表明:针对氟离子质量浓度为0.1~1.0 g/L的含氟模拟溶液,在溶液初始pH为3.0、氯化镧用量为理论量的1.3倍、反应温度为50 ℃、反应时间为10 min条件下,除氟率达95%以上,除氟后液中剩余氟离子质量浓度低于30 mg/L,符合国标规定的氟化物排放限值。该法在较宽的氟浓度范围内具有较好的工艺适用性,具有一定应用价值。

In order to solve the problem of fluorine-containing water pollution, lanthanum chloride precipitation method was used to remove fluorine from it. Through in-depth analysis of the chemical characteristics and thermodynamic reaction mechanism of the solution, the interaction between La3+ and F- in aqueous solution was revealed. The effects of initial pH of the solution, the amount of lanthanum chloride, reaction temperature and time on the removal of fluoride were investigated by single factor test, and the optimized process parameters were determined. The results show that for the fluorine-containing simulated solution with fluorine ion mass concentration of 0.1-1.0 g/L, under the conditions of initial solution pH of 3.0, lanthanum chloride dosage of 1.3 times of the theoretical amount, reaction temperature of 50 ℃ and reaction time of 10 min, the fluorine removal rate is more than 95%, and the residual fluorine ion mass concentration in the liquid after fluorine removal is less than 30 mg/L, which meets the fluoride emission limit specified in the national standard. The method has good process applicability in a wide range of fluorine concentration and has certain application value.
