质量认证水的可用性与食品和药品的生产有关。水中锰含量对容器和反应堆腐蚀的不利影响要求在将工艺用水用于生产工艺之前，必须仔细检查工艺用水的允许浓度水平。在这项研究中，优化的吸附工艺条件密切相关的去除锰的生物处理棕榈油厂废水（BPOME）使用沸石3A随后与斜发沸石的比较吸附进行了研究。研究采用响应面法（RSM）的面心中心复合设计（FCCCD）。响应面二次模型的方差分析（ANOVA）显示，该模型与剂量和搅拌速度具有显著性，暗示了优化的主要显著工艺因素。由该模型得到的R2为0.9478，与预测的R2一致。Langmuir和准二级动力学表明吸附机理涉及单层吸附和阳离子交换。
Availability of quality‐certified water is pertinent to the production of food and pharmaceutical products. Adverse effects of manganese content of water on the corrosion of vessels and reactors necessitate that process water is scrutinized for allowable concentration levels before being applied in the production processes. In this research, optimization of the adsorption process conditions germane to the removal of manganese from biotreated palm oil mill effluent (BPOME) using zeolite 3A subsequent to a comparative adsorption with clinoptilolite was studied. A face‐centered central composite design (FCCCD) of the response surface methodology (RSM) was adopted for the study. Analysis of variance (ANOVA) for response surface quadratic model revealed that the model was significant with dosage and agitation speed connoting the main significant process factors for the optimization. R2 of 0.9478 yielded by the model was in agreement with predicted R2. Langmuir and pseudo‐second‐order suggest the adsorption mechanism involved monolayer adsorption and cation exchanging.
