A study was conducted to examine the potential of jute processing waste (JPW) for the treatment of wastewater contaminated with dye and other organics generated from various activities associated with jute cultivation and fibre production. Adsorption studies in batch mode have been conducted using dye solution as an adsorbate and JPW as an adsorbent. A comparative adsorption study was made with standard adsorbents such as powdered and granular activated carbon (PAC and GAC, respectively). A maximum removal of 81.7% was obtained with methylene blue dye using JPW as compared to 61% using PAC and 40% using GAC under similar conditions. The adsorption potential of JPW was observed to be dependent on various parameters such as type of dye, initial dye concentration, pH and dosage of adsorbent. The batch sorption data conformed well to the Langmuir and Freundlich isotherms. However, lower BOD (33.3%) and COD (13.8%) removal from retting effluent was observed using JPW as compared to 75.6% BOD removal and 71.1% COD removal obtained with GAC.
开展了一项研究，以考察黄麻加工废料（JPW）处理受染料及其他有机物污染的废水的潜力，这些废水源自与黄麻种植和纤维生产相关的各种活动。已采用染料溶液作为吸附质、JPW作为吸附剂进行了间歇模式下的吸附研究。还与标准吸附剂（如粉末状和颗粒状活性炭，分别为PAC和GAC）进行了对比吸附研究。在类似条件下，使用JPW对亚甲基蓝染料的最大去除率为81.7%，而使用PAC的去除率为61%，使用GAC的去除率为40%。观察到JPW的吸附潜力取决于多种参数，如染料类型、初始染料浓度、pH值和吸附剂用量。间歇吸附数据与朗缪尔等温线和弗伦德利希等温线拟合良好。然而，与使用GAC时获得的75.6%的BOD去除率和71.1%的COD去除率相比，使用JPW时从浸麻废水里观察到的BOD去除率较低（33.3%），COD去除率也较低（13.8%）。
